^ i dont know from experience, but ive heard the 550ti isnt really worth the money. the 560ti, however, is what i have, and i can pull a solid 60 fps anywhere in battlefield 3 with everything on high with that post AA thing off. idfk what that is but it fucking annihilates my frame rate.
the 560ti is also like 70 bucks more expensive though. but seeing as hes going for a 7970, something tells me 220 dollars is within his GPU budget, lol.
