Should I get 2 XFX 6870 or should I get EVGA GTX 460 I heard the SLI 460 has micro stuttering or dips in FPS and I want these cards to last until GTX 6XX or HD7XXX series cards come out. So what do you guys have to say about those in crossfire are they better I mostly want to play BF3, Skyrim, Diablo 3 maxed out. Also is the 2GB version worth paying more for I heard games are using above 1GB now in 1920x1080 monitors like Crysis? Help me out guys before I buy!
