Yeah, I don't really want to go back to 7 on my desktop (all the other crunchers still run 7 or Ubuntu 12.04 LTS). AMD's drivers still suck under Windows 8 as well and I get a BSOD every 2-3 days with AMD's typical Kernel-Power event BSOD or whatever it is. My 7950's fans still turn on/off randomly when the computer hasn't been touched for a while, and they make an extremely annoying jerk/shudder noise every time they turn back on in the middle of the night. Anyone know how many WUs a GF104 or a GF100 can run, and is it easy to set up 2 cards to crunch along with the CPU? I don't want to move off of F@H completely, but I probably should have jumped on the HCC GPU bandwagon from the get-go.
