I just started mining in July this year. We (my wife and I) got the parts build a 6 x 1070 rig on July 22, we got all the 1070 cars for $399 each and
had it up and running 3 hours later.
How difficult are the AMD rigs compared to the Nvidia rigs.
Please sell me on a AMD rig for Cryptonight! or another algo (maybe get another nvidia rig?)
Thankds
AMD rigs may involve a bit more configuration because of the need for BIOS mods and whatnot but the primary trade-off is that you get more hashrate and less power consumption. Of course it will depend on your GPU but generally its safe to say its more profitable.
Like what previous posters said, I personally recommend the Vega 56s, if you can get them at around $500.
The stats I posted above are without bios mods. 1900 h/s and 180w power draw. The only thing I did was windows reg edits to reduce power consumption from 230 to 180 per card.
