Hi kqpahv,
I have a question for you: just how do you manage your 18 rigs for folding? If I understand right you have all AMD cards and thus you have to use Windows. I can't still image how difficult it was to maintain more than 3 rigs with Windows. Btw could you share what kind of CPU and how many cards do you use for your rigs?
