Hey guys, was just wondering some opinions, right now i have a single 5850. It's not really giving me the frames I want, considering I play at a very high resolution. my question is this, would it be worth it to buy a 5970? or are the nvidia 480's any good, would those be worth looking into, I bought a 5850 and XF both of them, and it gave me like 9 more fps. I want a card that will destroy these games. I know that some games don't support XF, is the 5970 conisidered an XF to games or would both GPU's be used all the time?
