I've been lurking on this board gathering info, and have parts to start building my first rig.  Found old computer parts laying in my basement, Pentium D CPU, with 4 gig of ram, and the motherboard has 2 PCIe ports.  So I have an Asus Raedon RX 580 on its way (the 4 gig version), and am tempted to buy a 2nd 8gig version and run both.  but for now just the one.





Based on what i've seen the has rate on this card is somewhere around 24MH/s.  when I type that into a calculator I find I can mine ETH for about $40 a month...  When I calculate BTC I lose $8 per month.  My question is, I know that GPU mining is mostly dead for BTC, but am curious about the different ATL coins.  does the 24MH/s stay consistent when looking at different Altcoins?  or when mining some, does that hashrate go down depending on the currency being mined? 

the hashrate depends on the algorithm of the coin
some data for rx580 on different coins
on eth it can do till 31 mhs
on zcash it will do 270 sols
on xmr it will do 800 hashes

Thanks!  Is there a big difference between 4 gig cards and 8 gig cards?  I can get an 8gig version of this card for about $60 more...

Also, if I wanted to do 2 GPUs would I be better off doing 2 of the RX580 cards, or keep the on 580 I have, and add a GTX 1070?

270 H/s on Equihash is way too low for a RX 570/580. I get 310 H/s+ with a RX 570  and 325 H/s with a RX 580.

I also get ~900 H/s on XMR with the GatelessGate.

$60 more is way too much to pay for 8GB cards. I usually pay ~$25 more for 8GB cards of the same brand and model. 8GB GPU's usually will have faster memory than 4GBs, but for the most part, there is not much difference in hash rate between 4GB and 8GB GPU's of the same model. The benefit of 4GB cards is you can buy more cards for the same amount of money, so you will get a better hash/$ performance. The main benefit with 8GB is slightly better dual mining performance, more overhead for future Dag file growth on Ethash coins like ETH/ETC and better future resale value.

That helps a lot too!

Last question...  for now I hope.  I have a radeon 580, I'm thinking of a 2nd card, I can get another 580, OR I can get an nvidia GTX 1070.  the 1070 is about $200 more.  it is the normal 1070 not the 1070 TI.  is the 1070 worth the bump in price?

I would go with two RX 570 4GB cards at $250> each for $50-70 more than a single 1070. Two RX 570 4GB cards are more profitable/$ than a single GTX 1070 on most algorithms.

and what this fool doesn't tell ya is 2 amd gpus is gunna use bit more power than just 1 gpu like the 1070, the 1070 also hashes WAY faster than a 570 does, depends on the algo though unless you fully mod the bios of the amd gpus

I hear ya.  I looked ad the anticipated hash rates and see the 580 is at like 24 or so, and the 1070 is at 27 or so.  Just wasn't sure if its worth $200 more for 3 MH/s  however those are just based on numbers I saw online, so I could be off.

Is it true that some coins mine better with AMD others mine better with Nvidia?

The fool is whoever thinks for ~$50-$70 difference a single 1070 is as profitable as two RX 570's 4 GB $250>

Two RX 570's on Equihash ==> 620 H/s @130 W each. ROI 143 days

One 1070 on Equihash ==> 500 H/s @ 150 W ROI 150 days

And that is on ONE OF THE BEST algorithms to mine with a 1070.

On ETH it's not even close or are you too lazy to backup the original Bios with AtiWinFlash, download PBE v1.62, click 'one click timing patch' and flash the Bios back to the card. LOL

Oh, is the Asus Z170-PRO a good motherboard for minning?  I see it has 7 PCIe slots, figured 7 GPUs?
