thanks for the reply, yeah im running the 12.11 Beta Drivers already. my PSU is 1000w, I was running 1gb 460s in SLi previously and I think they ate more power than the 7970.
Im just looking at other peoples benchmarks on Farcry3 or Hitman and they seem to be getting a steady 60fps on hitman.
im on about 45-50's in hitman with no AA, and about 20-30fps on farcry ultra settings with Multisample anti-aliasing at 2. So it's pretty pathetic really. I decided to turn off AA in farcry but it looks pretty lame & I didn't think I would have to do that as other people haven't.
