Folks, if you would invest 20K USD in GPUs, what would you buy?
I prefer NVIDIA cards.
Some people say 1060 3gb is best ROI, some say 1070 and someone 1080ti ...
If we consider of long time investment and better quallity of work, what would you buy?
NVidia GTX 1070 are the best choice, with the best ratio ROI.
If you want extra pleasure with hardware, you can buy also some GTX 1080 : the ROI is not so good than GTX 1070, but you have the possibility to play with a SLI, after mining is over, even in 2 or 3 years.
1070 at $430 for a good one vs 8GB AMD 580 for $300 ?
I would go the 580 route, save 100 per card so you get a free one every three you order compared to the 1070, plus 580s can be tuned to use lower power and are great for dual mining DCR
i.e eth 29 or ETC 29mhs and DCR like 900 for 150 watts will beat out a 1070 for ROI
All GTX 1070 are good and the mid price is not $430 but $350.
And the forumeur wrote "I prefer nVidia cards"... and he's right : AMD sucks and need a lot of electricity power/cooling.
