Hi All, Firstly i am a fan of ATI .. have owned ATI cards all the way up to the 5970. Then switched to nvidia 480s -> 580s. I must admit the reason i changed was drivers (3 screens and crossfire at the time was not so good) and not the performance of the card. My brother has bought dual 7970s which have been waterblocked with swiftech komodo blocks. I have not used his machine much but not matter what settings / drivers he uses he does not seem to get a good run without troubles. It crashes on the desktop , crashes in dirt 3 , odd crash in max payne 3 although better. This is all without overclocks. One card seems better than two if he disables crossfire although its not ideal. Hes got that sick of it hes looking at selling the cards and either buying a single card or SLI. Hes offered me the cards cheap, so its pretty enticing as i have 2 GTX580 hydrocopper 2s atm. So i'm wondering is the devil i know better than the devil i dont ??? I run 1 screen , 2560x1440 and i'm not too fussed on Physx etc.
