I have one HD 7950 right now and I have a $500 upgrade budget and all these solutions except to HD 7950 crossfire cost about $500. I know Crossfire has microstutter issues and that going SLI would mean more heat and such, but I'm not really that concerned since it will be in a Corsair Air 540 case (Hint:Great airflow) AAnyway, The Sli 760 will get me the most performance I'm thinking but what do you guys think?
