Lets be honest here are you going to play with 4xMSAA? Do you have to? If not then you'll be fine. Funny thing about BF is i had been playing it on my 470 (BF3) with textures on ultra and everything else on high and it looked great and ran great. I play on ultra now with my 7970 but i honestly would be hard pressed to tell the difference most of the time without looking closely.
