Im using 12.1 drivers and latest cap. thier is no mass effect 2 xfire profile so which would be best for this game and other games without a predefined profile?

My specs are i7 980x @ 3.33ghz

                      2x 2gb 6950's in crossfire

                      12gb ddr3 1600mhz mem

                       win 7 64bit

                       Mainboard? Dunno im on an alienware pc desktop but this would be the main guts of my pc.

Also battlefield 3 runs slow, ever since post 11.11 drivers. the games runs and look fantastic but the 11.11 drivers made the game for me run smooth.

Best bet is to run with the neither afr friendly or optimized 1x1. You can always try afr friendly, which will give you better performance if it works, but if you run into flickering issues, etc., go back to the "default" profile.
