so you have roughly $1275 USD. Ethereum is obviously profitble but with growing difficulty and the looming POS I wouldn't recommend going for a cost effective Eth rig like 280x or 270x. I think you would benefit from a more well rounded 3 GPU rig that can has well on other algos. Research R9 290x(great for ethereum) or GTX 970 Strix edition, can find them both used-refurbed-new from $300-$400 grab 3 of those, a MOBO with at least 3 PCI-e slots, most likely 3 risers depending on the board. Mediocre CPU (no more than $50). 50gb-100gb HDD/SSD. And windows if you are going that route. It would be cutting it close on budget, but I think you would benefit more from that more than say a 6 280x refurbed rig.

Do you have any dual or quad core,8gig ram PC's (parts) layin around with a 750 watt psu Huh

If so you just need a vid card or two  Grin

Here's a good list to look for a card :

I would think if you have no prior knowledge on how mining equipment works, then I would suggest that you buy a pre-configured system so that will simplify things to get you going.
Then once you get the hang of it to upgrade parts on it to tweak it so to have it running at it maximum capacity.

you can buy with 250 euro or usd all the thing minus psu and gpu, then you decide if you want few gpu you buy a little psu so around 100? and what remain for gpu

anyway this is my daily usage computer maybe i will use it for mining
ASRock Motherboard Fatal1ty B150 Gaming K4/D3 + I5 6400 + ram corsair 4gb + FSP aurum 700watt 80+gold
must i upgrade my ram ? PSU ?
before buying new VGA for mining

i will use my old cpu ddr2 to daily usage

and which algo can i mining with gpu...?

Ram is good,have to see what vid cards you get,but that 700 watt PSU should be good for up to 3 midgrade cards (not the 290,390,7990 kind,only maybe 2 of those).

If you can build a PC from free scraps,like I did & do,you just buy a vid card...you can always sell it & get alot of your money back later on  Cool

You have to do the homework,there are sooo many coins to mine,but which one will make a profit...is anyone's guess  Shocked

Keep looking in this forum for GPU only coins,Eth is good ATM...x11 coins...x13 coins...many others...google is your friend in this too  Wink

3 bitcoin is about $1250. So you can buy 3 R9 390 and other components to mine the Ethereum.

AMD R9 390 has 8 GB memory, so it could be useful in the future mining. But the ROI might be longer than cheaper cards.

you can not, 3 390 alone cost around 1k, and the psu cost 250 at least, so you need other 250....

Start with 2x390 and make some profit. Use the profit to buy another 390. And increase the farm this way.

I looked through that list on Newegg a few weeks ago & found a Sapphire 380 4gig for $194.99,they offered a free game (nothing to me),but they offered a $20 gift certificate(we have a winner!!!).

So after I bought it I got 3 day shipping for $4.99,total=$199.98,after gift certificate =$179.98  Cool

It mines stock at 20-22mhs at 57c fan at 80%.ROI in about 2 months (with my paid off 7970 helping)  Wink

I don't see spending $250-350+ on a card ATM,the mhs per dollar is what I used to decide on the 380 (bang for the buck).

The 380 at $180= $8.18 per mhs....the 390 at $390=$12.58 per mhs,so it's up to you which is a better deal  Wink

I wouldn't buy any hardware at this point you wont likely ROI.  Buy 3 BTC worth of DCR and stake it, a gui wallet is coming out soon.

My current Ethereum mining rig cost me equivilent of a bit less than 2 Bitcoin (not counting the power supply, that would probably put it a bit OVER) - but it wasn't intended originally for Ethereum so it's nowhere near optimised for mining.

 20/20 hindsight, I'd use a different motherboard and case - I've found a very few motherboards that DON'T put a PCI-E slot right at the edge of the motherboard (limiting that slot to a single-width card in every case I've seen to date), or they have 4 total slots spaced out so that 3 of them are fully usable for dual-width cards (abet a bit tight on cooling clearance) AND that 4'th slot that's only single-width-card usable.


 It's too bad nobody ever made any single-width card more powerfull than some of the AMD HD 7750s (especially the low-profile Sapphire card), or that case makers aiming at "high-end gaming systems" don't pay better attention to making that end slot USEFULL and leave enough space and the slots to mount a dual-width card in that last slot BY DESIGN.


 If anyone knows of any such cases, feel free to post/send me links!

AMD R9 nano is a short card, but it still occupies two PCIE slots. The power consumption is also larger.

R9 nano is a DUAL-slot width card - it's about the same size as my EVGA GTX 950 SC cards, perhaps a hair shorter but SAME width - that WIDTH is the issue, not the card length.

 It's a nice powerfull card (though works very poorly on Ethereum per every posting I've seen about it), but kinda expen$ive. From what I've seen it doesn't seem to mine Ethereum anywhere near well enough to justify the cost, as R9 cards at about HALF the price can match it's hashrate.

 I'd LOVE to have about 9 of them crunching RC5 though - that would be "instant #1 on the daily list" easy (my off-the-cuff ballpark estimate is that 6 would be a tossup in production for that #1 position).



 If you want to see a true SMALL card, look up the Sapphire low profile 7750 card - it's the most powerfull "TRUE single-slot" card I've ever been able to find info about (and as luck would have it I managed to buy one of the last ones Newegg ever had for sale).

 I don't know why AMD chose to ignore the 7750 when they did their "rebrand" on most of the initial R5/R7/R9 line, the best single-slot card in THAT lineup was only a 384 Stream unit card vs. the 512 on the 7750, and same issue with low-profile cards (which are the most likely to be TRUE single-slot cards this past decade and some).

AMD R9 nano is a very efficient card, but it is too expensive. It ROI days are about 60% more than the R9 390.

stop everything new cards are coming, and 1 of those is equal almost to two, but the info gathered on the web, this is insane! and they will cost the same, even better
