Re: need some advice before making a move
Dual 6800s should get the job done. Maybe you can overclock your gpus, while adding some more fans to keep it cool. The Zalmans do a great job from what I hear. Wonder if there is any thermal paste for gpus? Lol, I dunno just some suggestions. Stick with the 6800s though, and think every possible solution before you buy that 7900 gtx.
