And my budget on a graphics card is around $600 i dont know whether to get crossfire 7870's or crossfire 7950's or 1 gtx 680 4g with backplate or the new gtx 650 boost in SLI i just dont know what would be best

Also would like to know if you guys have suggestions on any of the other Parts Around $1500 Budget for whole build


Out of all of those the best performance wise would likely be just the 680... From what I've seen crossfiring two cards doesn't always yeild twice the power...

Also if you have the budget get yourself an EVGA...

wew 600?

maybe the 680 4gb or even a 670 FTW edition.

i personally wouldn't CF because there might be alot of compatability issues in games
