yea, i found that with that program the same, i overclocked quite a lot, and the game performance got worse but temps were same etc. Then i used ATITOOL 0.25 and it works a dream, temps are a bit higher, but it runs much faster (i gained 10-15 FPS in COD2). I used my 7900GS (yea it works with nvidia cards) from 440/660 to 625/800 with temps at idle from non-oc=49 degrees, to oc'ed=53
