I brought a couple of 1070 zotac minis. I will likely sell them before volta hits whilst they have high resale value.
I figured that ethereum (and other coins) could crash at any given time so its best to maximise monthly revenue whilst its possible.
I didnt go with 1080tis because I felt the extra mining capability was less than the extra capital outlay for each card, and also that it was above what I was willing to spend, AMD cards at the time I got the 1070s very badly priced. Although the new rx vega 56s may have now changed that now as they are priced reasonably.
The issue with the 56s is of course the much higher power draw, meaning more PSU power will be needed adding to capital outlay. Although an extra £30 or so on a PSU vs PSU needed for 2 1070s probably is offset by extra profits on the 56s, not the same as the 1080ti calculations with an extra £330 per card.
Note you can flash a 64 bios on a 56 to make the HBM2 performance match, so if you thinking of buying some gpus the 56s look a good bet now.
So about an extra 7mH which I think would increase with a 64 bios to maybe an extra 10Mh about an extra 33% hashrate for about 8% increase in cost per card over a 1070.
Also that on AMD cards there is better coins to mine than ETH as well. I think 1070 is the best nvidia card to get (not in agreement with giraffe I know), but the vega 56 seems a better bet from my perch. Dont get non ti 1080s
