I'm using a Phenom II X6 1090T, with and nVidia 480 GTX and 8 Gb RAM 1333 Kingston HyperX (I got it last Christmas with COD on my mind) and I think I need a much better PC.

I can handle a 6 vs 6 dogfight over the sea withe decent fps, but if I add more planes or fly inland... the game stuttering is really unbearable
