iv been playing bf3 beta for a few days and i will say its very good. my spec is 2500k 4.3, 8gig ddr3, asus 560ti top oced and i can play with the settings on ultra at 1080p.the game looks and plays great now, so when the finished game comes out the end of the month its going to be even better.
any one with a 560 ti update it in your bios. it helps with the crashing on these cards. download the update from your card manufactor
