I have a great deal to buy 10 - gtx 1080 at 539$ a piece brand new, another deal for 10 gtx 1070 at 459$ a piece.
I need some advice from people who own rigs of nvidia. Which one of these 2 would you buy and Does it worth to invest 5.5k in this deal ?
Thanks in advance!

I do go with 1070, I think you ll get faster ROI with them. Is it worth it? Well, it all depends on your power price. With all these new GPUs designed only for mining getting out, without DVI exit, combined with falling alt prices, which will probably continue thought the summer, mining profits will continue to shrink.

If you have high electricity price and no resell option, you might have a problem. Otherwise, go for it.

You need to decide what are you going to do with them after if all go to hell. I'd say go with the 1080, for now mine equihash, if that goes to hell too then sell them later before volta cause if you take too long to resell them then you will not find a good price for them.

The GTX 1070's are overpriced for a quantity purchase.  Last two I bought a couple days ago were $404 each.  Just watch for deals and inventory.

Between the two though, I would probably do the 1070's even at that price.  10x 1070's should net minimum $50 a day so your looking at 110 days to ROI max.

The price for 1080 is really good, i might be able to negotiate a little if i buy more.
Is there a difference in hash rate between these 2 models 1080 ?:

I did a quick test with 1070 and 1080 with nicehash miner and 1080 seems to perform better by about 1.50$/day. Anyone experienced the same ?
Thanks in advance!

i would also check the price you get for 1080ti - it's from Sol/$ MH/$ like the 1070 but you need less of them - if you can get a good 1080TI (e.g. MSI X Version) for ~ $ 700 i would go for that.

i dont think 1080/s are worth it ... u get for 700 usd almost 2 1070s and the hasrate for the 1080 isnt almost doubled ;D i think its something like 600-700sol/s on ZCash where 1070s has 400-500sol/s

I was doing 660 sols yesterday on NiceHash. I have the Asus GTX 1080 Ti STRIX.

Is that still accurate?
I'm doing 68.916 MHS on Lyra2REv2 NiceHash right now with my GTX 1080 Ti.

For the price you listed, the gtx 1080 has no competition.

Things must be rough where you live if you consider $540 for a 1080 and $460 for a 1070 a great deal. You could buy two of the RX 470 4GB mining cards for $500 or the gaming RX 570 4GB cards for less than that, if you can find them and get roughly 20-30% more hashrate for the same price.

I'll go for 1080 in bulk. Right now i have msi godlike carbon motherboard and it has only 5 pci-e slots. I have good deal to buy another godlike carbon motherboard but i want to ask you first, is it a good motherboard for setting a rig ? also some suggestions for gpu raiser ?

RX 470 8 gb price is 220 eur
and hashrate is up from GTX 1080

Gtx 1080 each day is more expensive,but 1080ti is better.

I would buy the 1070 cards, GDDR5 is better than GDDR5X memories for mining due to the low latency times.

And I wouldn't face this as an investment, this is a hobby.

Gtx 1080 certainly has the latest technology, but you must see in terms of needs and also your ability. I think the latest technology definitely has a much better feature. Investing money is certainly a difficult thing, you should be able to think about when the ROI will occur and what coin you will be mining. Whether the coin has a good prospect or not. So consider everything before you regret having spent a lot of money.

That is a high end lga 2011 v3 motherboard, x99 series have enough pci-e lanes, 5 gpu's will definitely work. About the riser, get any 6 version.

first of all you should be able to get some RX 470 8 gb which are on stock and sold at this price and what will you do with that cards in few weeks when they lose 30% hash power on ETH? going to one of the few alt-currencies (where for sure none of the other AMD miners will go to shred the profit there)? ;)

I would go for 1070 if I were you. They have the same Ethereum power for a lower price.

I'm buying bitcoins every month to pay for  expenses. i'm doing intense 3d programming and web sites and i use a lot of gpu memory. So i was thinking why pay lot of fee to buy coins when i can put this pc to mine when i'm not working and is idle.

Even if the epoch benchmark issue with the Claymore miner is not fixed or ETH goes to POS by that time, two RX 4XX/5XX card will easily do 620 H/s on ZEC or ~30% better than a 1070, or ~10% better than a 1080. Results for most other algoriths is similar. The bottom line is I can mine more coins for the same amount spent on cards with the RX 4XX/5XX than any Nvidia 10 series cards.

problem with rx is almost impossible to find here in california. all stores , even amazon is sold out.
only one model is available in bulk, this one:
https://www.amazon.com/MSI-GAMING-Radeon-RX-470/dp/B01KCWZHTO
it costs 699$ + tax, that's 150$ more than 1080.

why you compare TWO RX4xx/5xx with ONE 1070? you think you will never pay off the investment? In case you never can get the money back from investment it makes anyway no sense to start even mining ;)

After the investment is payed off you make with ONE 1070 ~ 470 Sol/s and with ONE RX4xx/5xx just ~ 320 Sol/s - so after investment is payed off, with which hardware you can mine more and get better profit?
Or say it in this way, with 4 x 1070 i mine nearly the same than someone with 6 x RX4xx/5xx ;)

in case i get the deal done, which you recommend: 1080 founder edition with 1 fan, or 1080 regular with 2 fans ?

I guess you missed or don't understand this part: The bottom line is I can mine more coins for the same amount spent on cards with the RX 4XX/5XX than any Nvidia 10 series cards. Even after the cards are paid off, I will still make more coins going with RX 4XX/5XX than I can buying 1070's or any other Nvidia 10 card and if the profitability drops, I will still be able to make a profit where a single 1070 won't.

GTX 1080 have a special memory and this memory don't work well for mining activity.
Then 1080 hashrate is not better than 1070's hashrate and they eat a lot of watts more.
Sometimes, 1080's hashrate is lower than 1070's...

and you don't understand that what is the advantage from lower investments AFTER all investments are payed off?
you still pay for your cards something (beside power)? after the cards gone after they are payed off and you have to buy again new one for lower investment?

How much money do you make with 6 x RX4xx/5xx AFTER all your investments are payed?
How much money do you make with 6 x 1070 AFTER all your investments are payed?

Just two simple questions ;)

Your calculation would just be right if you permanently invest into new cards over and over again and throw them away after they are payed off :)

No Question about it.  There is ABSOLUTELY NO VALUE IN 1080 Especially mining ZEC.

ZEC - 1070 - Asus Dual 8gb OC - I have 40 cards of this in 5 rigs.  Its AWESOME.  This card can be bios modded to install ASUS Dragon Bios and it will give 450 MHS/S - 1 Rig of 8 is 3400 HASHES Guaranteed.  

PROS of 1070

Majority is SINGLE 8PIN.  Very important for LONG term MINING.
Much cheaper than 1080 for less than 100 hashes Difference.
the BEST Nvidia card there is for mining.

1080ti is also better ROI than 1080.  Its close to 1070.

Date            Card        Hasrate       Power
11-May   7x1080ti   4520       1520
15-May   7x1080   3500       1380
11-May   7x1070   3325       1050
20-May   7x1060   2030       870

This is Minimal Optimization.

Two RX 4XX/5XX will make more profit than any single 1070 or 1080, whether the cards are paid off or not makes no difference in the profitability of the cards. A quicker ROI is an added benefit that comes from the cards being more profitable to mine with. Take ZEC for example, two RX 4XX/5XX will currently make $133 a month compared to $104 for a single 1070 after the power consumption is factored in.

If the difficulty doubles from where it is now. A single 1070 will make $53 a month vs $66 a month for two RX 4XX/5XX cards.
Which means it is more efficient and profitable to mine with RX 4XX/5XX cards than it is to mine with Nvidia 10 series cards.

2 or 3 fans, never 1 fan, mining needs cooling and 2 or 3 fans is ideal, 2 fans if noise bothers you.

imo, 1080 at right price, you get a card that will hold some resale, (1070 wont, theres WAY to many of them out there), and DENSITY matters
everyone can argue 1070's are better price to performance, or that two RX cards is better than a 1070 but jesus man think DENSITY

i gurantee you your ROI will catch up when others are building WHOLE nother rigs, just to have EQUAL hashrate as your 1080+ rigs

short-minders i tell ya people are haha

i am upgrading my 1070's to all 1080ti now, going long, DENSE solid high-hash rigs, then i dont need 25 new rigs, my FIVE will be as powerful. i will ROI b4 Volta is in our hands on the 1080ti, guranteed. and they will hold AWESOME resale still in 3-4 months (tho i will hold mine to mine with unless volta looks THAT good)

Good Luck on your choice!

If you can tell me where you get your RX4xx/5xx for a dream price of $ 220,-- i take them all - throw them for $ 300,-- ebay and laugh at the dealer who sold them to me :D

What if i could get 1070s for $ 110,--? i get even twice  and make 1/3 each card more profit :D

I am currently mining zec with 4 1070 at 3 usd per card.


Are there some more profitable options right now?

i'm also with the other that say to go with the 1070, it's better overall, there is no algo that the 1070 can mine bad, instead the 1080 have some algo that can not be mined very well, like ETH and feathercoin

Right now the most profitable option might be to hold your ZEC and place sale orders for $ 350 or higher and wait some days ;)
The main other currencies are on low rates too, you might could mine some HUSH or FCT too when their difficulty rates are going down (just take care as they go up/down several times a day).

This.  Having both 1080s and 1070s working I find the 1070s almost match the 1080.  I cannot speak about special memory, but performance is darn close, and I can tweak the 1070s down to under 110 watts and get almost the same numbers.  I only bought a couple 1080s so when I retire them I can run them in a game rig, but they pull more power and are barely better.

Also $459 for a 1070 is very pricey.  Look for prices more like $400 to $420

I'm about to meet the dealer to buy 16 pieces 1080. The final price is 9000$ out-the-door
What do you guys think ?

What about the gtx 1070, ask him the price for 16 of them. GTX 1080 at $539 was a good price, for $30 more is not worth. Actually as you are buying many, a final price on the GTX 1080 for $530 a piece would be the deal.

gtx 1070 is 400$ but only 4 available

Get only the 4 and wait for others 1070 to be available, for $400, the gtx 1070 is a much better card.

what do you think about gtx 1070 hybrid ? are they good ?

1080ti : )

 Nobody is selling the RX 470 mining cards for $250 - the NewEgg postings were mistakes, they don't even have the cards yet - and the rep I talked to was pretty sure they were NOT going to actually sell the things at MSRP or even close when they DO get them.

 If you can get GTX 1070 at $400, GRAB THEM - that's bloody cheap at current pricing, and is the same ballpark they were in a month ago before the started getting impacted by the "mining caused GPU shortage".

 Last time I checked NewEgg (yesterday), for example, the LOWEST they had a "in stock" GTX 1070 listed at was well over $500, and most were $600-$800 of the VERY FEW IN STOCK options they had at all.


 BTW - they didn't have ANYTHING in an RX 470/480/570/580 for under $500 at all, and only 1 or 2 options under $600 - at current pricing the RX line has ZERO advantage in reaching ROI over the GTX 1070.

 Trying to call those cards "$250 cards" is not valid and hasn't been for a month or two now.

The rep you spoke with is incorrect. The mining cards were in stock at Newegg and limited to one per person for $260 for the Samsung cards and $250 for the non-Samsung version. They are still listed on the website and you can sign up to be notified when they come back in stock.

https://www.newegg.com/Product/Product.aspx?Item=N82E16814202283

This morning Newegg also had Nvidia 1070's for $399.99 and others at $429.99, limited to one per person. Several places have had the regular RX 570 4GB cards at less than $250 over the past week. You need to act fast because they sell out quick.

http://www.nowinstock.net/computers/videocards/amd/rx570/

these are 4gb cards. you can find 4gb anywhere. for mining, ideally would be 8gb at least. today i bought 16 evga 1080, i'll post later how they perform.
I noticed amazon sells 1080 cheaper than 1070. Suppose you find 1070 and 1080 at the same price, which one would you buy ?

That is not true. The Dag file won't be even close to 4GB until 2019 and the diffrence in hashrate between the the 4GB and 8GB is less than 1 MH/s. In fact two of the Powercolor Red Dragon RX 570 4GB cards that I bought for $190 each less than 3 weeks ago will do over 29 MH/s and I have 8GB cards that only do 28 MH/s. Just because you think it's a good deal to buy overpriced cards for the performance they have in mining compared to ther cards doesen't mean they are a good deal. The fact that you would buy 16 1080's without even knowing how they perform in mining only shows you don't have a clue.

https://imagizer.imageshack.us/a/img922/5904/lYQF1I.png

And what if we are on dag 199 with those 4gb cards?
The 8gb versions don't seem effected but the 4gb's will hurt a lot.

vann: each 1080 is making about 5-6$ per day. as i said, i'm doing intense 3d programming and i use lot of gpu, i only put them to mine when pc is idle. i think 1080 have better resale value for long term than 4gb cards.
how much are those 4gb making each ? i would be interested to see how they perform on nicehash

Yes, they are good, people dont buy it cause is just too expensive.

gtx 1080 ti has almost double the hash rate of 1070, and doesn't cost double.

gtx 1080 ti is only good for dgb, pay attention that concerning any other algo, a ti and its 352bit does not help much, now if the ti had 512bit then maybe it could have double the hashrate but then again it would cost 999 ~ 1200 usd, nvidia would not sell it as cheap as they sell the 1080 ti which if you bargain can be yours for 650 usd, the 1070 is the better card here hands down if = 400 usd.

I think the 1080 Ti makes more sense long term. After ROI you will make more with it over a 1070 and other coins it doubles the power. The initial investment is almost 2x as much though. I went with 4x 1080 Ti's for my current build of which I am mining LBRY.

You have a point and you are not wrong or right, everything in life have plus and or cons and that depend on many things, for me, at $400 the 1070 is a better card overall.

1080 ti is great long term option, but obviously depends on your budget. There are some great deals on used cards so I would suggest to look for used ones, but be careful of faulty cards. Although it probably isn't a major problem.

There doesn't seem to be any major cards coming out from Nvidia until next year. However AMD is releasing Vega cards so I would keep my eyes open and follow the GPU space.

 I had one of the mining cards ON ORDER - and the order was cancelled "as the cards had not come in yet".

 It would be nice if the RX series cards and the GTX 1070s are starting to drop back down towards MSRP - but I've not SEEN that to date, and the availability is still nearly nothing.

Yes
1080 ti is great long term option - but when Vega shows on market - price maybe drop

That depends if it can dethrone the 1080 Ti which I don't think it will be able to. If not NVIDIA will keep the prices where they are at most likely. Maybe the 1070/1080 will see a drop.

I own 1060's, 1070's, and 1080 ti's.
Saw no value in buying 1080 for the price vs a 1070 for eth/zec.
IMHO 1080 ti is the best card to go with at this point..

I plan on adding more 1070's for the right price sometime soon..

Edit: Just to note, my 1060 rig is one of my favorites.. extremely low energy and stays very cool..for the work it's done so far, at the price. Couldn't be happier.. but this will change with growing diff. for eth

Hello,

now i can find 1080 at 50$ more than 1070, the prices of 1070 are really high.

I consider looking at whattomine.com 1080 has more hash in all algo.

So is really better to go for 1080 instead 1070 ?

What about KHash/W ?

What about stability are a 1080 rig stable ?

With signatum i have around 280/299/KH/s with 1080ti and 270 with 1070.

My vote would go to 1070 as well. While 1080ti is a killer for Signatum. Sigt will be going POS soon so keep that in mind.

Why your vote is for 1070 ?

Looking at whattomine 1080 give more Hashes so it will ROI faster if it cost little less than 1070 also in other algo.

1070 would be a wise choice when you do make see on the hash specially on ETH mining they do have nearly the same hashes which it would be wise enough to choose 1070 for lesser price and you would really saved up but on general speaking on some coins 1080 would really have the edge.

You need to look at relative pricing in your country.

As I posted in another thread, the 1080 (at least here in the UK) is priced 10-20% higher than a 1070 and 40% lower than a 1080Ti.
I hashes over 20% faster than a 1070 in anything but Ethash and only approx 25% slower than a 1080Ti.

The 1080 has the best bang for the buck.
