Great program! My only problem is that the gpu test dosent work properly with error checking, but when in full screen it does work with crossfire! If I just had crossfire with error checking I would be in heaven. I just did the psu test and realized it's time to pop my pc p+c 750w back in that I just got back from an rma. Im getting a little much of a ripple with my BFG 800w, like ~1% to 1.5%.
