Hello, I'm new to computer gaming I'm on a budget I had three cards in mind one is the amd radeon 6770, 6790 and 6850. My budget is 130 but i'm tempted to buy the 6850. Im mostly going to play crysis 2, mafia 2, mass effect 2, GTA IV. I want to play in my 32 which only does 1440 x 900. Which one will give the best performance
