Given your reported hashrate, you are probably mining ETH (or one of the ETH spinoffs like ETC) and then Nicehash converts the ETH you mine TO BTC.

 You are not mining BTC directly - your hashrate would be a LOT higher but your income would be a LOT lower.


 I would suggest reading up on how Nicehash actually works - they are a "market" much more than they are a "pool".

ETH has a much larger DAG file, which hammers hashrate on the R9 280x (and other Tahiti-based GPUs).

They won't be obsolete after mining - there will be some small value to folks running dual-card Crossfire setups or folks with directX 12 games.

 Resale value is not likely to be GOOD though.


 Per my discussion with the NewEgg rep, it appears that the card I ordered never was in stock - "yet" - and is due sometime in July.


 I've not noticed much effect on GTX 1080 pricing yet, but it HAS been shifting a bit on the bottom end and availability seems to be dropping.
 EVGA earlier today only had *2* of their GTX 1080 models in stock on their webstore - it's not just NewEgg - and I am pretty sure that EVGA bumped pricing a little on at least some of their GTX 1080 models vs. a month ago.

 Haven't seen any effect on the GTX 1080 ti.
 YET.

Either they didn't have much stock, or it was never actually in stock at all like the one I TRIED to order that had Samsung memory.

Minor irritation that they kept my Bitcoin, but they issued me a "store credit" and I spend enough on Newegg often enough to find that acceptable.

 pool.burstcoin.biz usually has worked well for me - and other factors considered, I'm not sure if the problems I've had with them when I've HAD problems with them was on their end or might have been a flaking-out router on my end.

Possibly - and I didn't plot it as one file as I hadn't been able to get gpuplotter to work at ALL and wplotter always wants to plot to a /plots directory UNDER wherever it's installed.

 I might try replotting at some point - the machine it's in has a pair of RX 470, which hopefully will work a LOT faster than the one machine to date I DID manage to get gpuplotter working on (3 x GTX 1070 at 300something - not 3k not 30k 3 HUNDRED something nodes/sec wasn't exactly impressive).

 I thought wplotgenerator did optimised plots by default though?

 (edit) nope, it doesn't - but the good news is that I had enough HD space on another drive on that machine to optimise the existing plots, one at a time - and none of my other machines have drives big enough to be an issue yet.
 Mining is going noticeably faster already with just 2 TB of the plots optimised (except when I'm running the optimiser, or copying the result back to the plot drive).

Try finding ANY GTX 1060 at $300 or less TODAY.

 "Earlier this month" pricing hadn't started skyrocketing yet, especially if it was the first week or even the second week of June.

Depends on the project.

 For MooWrapper, AMD was a lot better due to competative hashrates at a much lower price point up to about 2 months back, now it's much closer. Memory speed does not matter, it's ALL about cores x core clock.
 Examples from my own farm and benchmarking - the R9 290 is good for a little over 4 Gigakeys/sec (1100 core), the GTX 1070 right about 4 Gigakeys/sec (I think I had core bumped up 100 Mhz in afterburner on that test), the RX 470 a little under 4 Gigakeys/sec (+100 core in AB), the R9 280x a little over 3 Gigakeys/sec (1100 core).
 The king right now would be one of the "dual" cards like the R9 295x2, which should be capable of around 9 Gigakeys/sec - but counts as 2 GPUs - with an honorable mention to the GTX 10080ti that should be capable of about 7 Gigakeys/sec (I just got one of those but haven't had time to do any actual testing yet). I think the Fury Pro would also be ballpark 9 Gigakeys/sec but I don't know how high you can overclock core on those.
 The new Vega Frontier should in theory be capable of over 9 Gigakeys/sec and possibly 10+ if it overclocks at all - but those cards are EXPEN$IVE even by current gouge pricing standards.

 For Milkyway, Double Precision Floating Point performance is what matters - which makes the old Tahiti-based (and to a lesser degree the old Hawaii based) cards like the R9 280/280x/290/290x/295x2/390/390x (but NOT the 390/380x) and the HD 7990/7970/7950 the best price/performance options even at current inflated pricing for ALL AMD "good mining" cards - their ONLY competition is high-priced workstation-specific cards from the Tesla and Firepro lines.
 The RX 580 for perspective has less than HALF the performance of the Hawaii cards, and closer to ONE THIRD of the Tahiti cards.

 Other projects - depends on the project and I don't know the specifics.

 Being realistic, don't expect to make good money from GRC as a researcher - it's been good for paying the electric for a year or so, and the last couple months it's actually been profitable, but you WOULD make a lot more on most cards from mining with them.

 I crunched the numbers on my current "big MooWrapper" rig today - pair of R9 290 and a A10-7860k, which happens to be the #1 computer on MooWrapper right now - it pulls in about $2 a day NET after electric usage at current GRC and Bitcoin pricing, while crunching very close to 9 Gigakeys/sec between the 3 GPUs (I don't use the CPU side of the APU for Moo on that rig, as it power-limits the GPU if I do and drops overall hashrate).

 Options are:

 BIOS modded RX 480/580.
 BIOS modded RX 470/570 will get into the lower end of that range.
 GTX 1070 will hit 30 sometimes 32 when overclocked, depending on the RAM.
 R9 290/290x/390/390x but those eat a lot of power.
 GTX 1080 will hit the VERY bottom of that range.
 GTX 1080ti will hit mid-30s somewhere.

 Note that ALL of these options are not exactly cheap due to the demand miners are putting on mid-high end GPUs the last 2-3 months.

 (edit)
 GTX 1060 6GB might get close to the bottom of that range - think it's 22 Mhs ballpark depending on how well the memory overclocks per reports.
 RX 460 won't get close to that range.
 (/edit)

 From what I've seen so far, the "mining edition" cards aren't going to be a LOT lower than consumer-model cards as folks "charge what the market will bear"....

First, the RX 470/480/570/580 got hammered.
Then it spread to the GTX 1070 as the "next best" ETH mining card, once the RXs got into the same price range.
Then it spread to the GTX 1060 as the "next best" option.
It seems to be having a small impact on the GTX 1080 due to ZEC miners liking those cards and the other good ZEC cards getting crazy-priced.

 For AMD, it was JUST as bad in late 2013/early 2014 during the great Litecoin mining craze - but back there there weren't a lot of other alternatives and NVidia cards weren't very good at mining Scrypt.
 X11 drug that out for a couple months, but when Litecoin price finally collapsed far enough the wave of "need something to mine" folks swamped Darkcoin (now DASH) and drove almost all the small miners (and some FARMS in higher-priced electric areas) back out of mining.

 This time around is a lot worse - ETH is worth a lot more and the profitability at it's peak about a week-and-a-half back was a LOT higher than Litecoin ever managed, other Altcoins also exploded and THEIR profitability was in the same ballpark as ETH (at least in part due to the "basket balance" tendancy), but many of those other altcoins COULD be mined equally profitably or even MORE profitably by NVidia cards - then the RX cards got crazy priced to the point that the GTX 1070 and to a lesser degree the GTX 1060 became competative on a hash/$ basis EVEN ON ETH to anything AMD.

 I also suspect this time around that the situation is going to last longer - the Litecoin / X11 craze only lasted a few months (perhaps 6 at MOST but that's pushing it a little) - the current craze is already 3 months or so in, and there was substantial mining ALREADY going on before the price jumps that started the craze hit.

 BTW - the older AMD cards are also strongly affected, try finding a R9 290/290x/390/390x for under $500 any more, and even the 7950/7970/R9 280/280X/380/380X are way up on price WHEN you can find them.

 Pre-Pascal NVidia cards seem to be mostly immune, except for use with some of the small-market-cap coins that have been traditional NVidia strongholds the last couple years.

And of the 3 Newegg lists, 2 are now out of stock again (the third one https://www.newegg.com/Product/Product.aspx?Item=14-202-292 was in stock but limited to 1 per person).

 I suspect the listing that was in-stock is the same card as the "4 GB Built with Samsung Memory" just on a new URL though.



 (edit) never mind, it sold out less than 10 mins after I managed to sneak my order in AND they canceled my order due to "out of stock".

Only those coins that use the SHA256 algo can be mined by "Bitcoin mining equipment" - Namecoin is probably the best known of those, but *right now* DGB and Myriad (both of which can be mined using one of 5 different algos) are probably closer to being profitable.

15 cents / KWH is VERY VERY HIGH for trying to make a profit on mining.
 Way too many major farms and even some of us small farms pay well under 5c/kwh and some get under 3.

Sapphire now has 3 of it's cards listed on Newegg.

 Only one in stock though was https://www.newegg.com/Product/Product.aspx?Item=14-202-292 and they're limiting it to 1 per person as of when I ordered mine - which I should have early next week.


 I figure I can at least get it MOSTLY paid for mining, and I have other uses for AMD cards long-term.

 I also don't see the "mining specific" cards having a big effect on pricing for a while - still too much demand for cards in general.

There are at least a half dozen threads on the "mining specific cards" on Bitcointalk - some Nvidia specific some AMD at least one for both.

 As it happens, I just ordered https://www.newegg.com/Product/Product.aspx?Item=14-202-292

 So at least SOME of the cards mentioned are legit.


 It doesn't appear to be AMD and NVidia themselves that are creating the cards - it's partners like Sapphire and ASUS (verified on their own websites and Sapphire has at least *3* cards listed on Newegg), Galax has also shown up in at least one video I think, MSI has at least one that showed up in a video, EVGA and a couple others are rumoured to be getting in as well but I've not seen verified info on those *YET*.

Blago doesn't use java and is specifically for CPUs.

If you keep the cards cool enough, they will last a long time even if overclocked.

 However, lifetime WILL probably be reduced as they'll run hotter than if you don't over clock.

Redundant thread, there are at least 3 others ALREADY on this subject.

Update to at least Afterburner 4.30 - older versions didn't work on the GTX 1070 reliably IF at all.

 Based on early benchmarks on real cards, these alleged hashrates are being shown to be fake news.

 So far the "mining specific" cards are pretty much matching the consumer-grade cards on hashrate.

 On the plus side, if optimised for it, they SHOULD use less power then the consumer cards, and they DO seem to be selling for quite a bit less than the current "gouge" pricing - when you can find the cards in stock.
