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
