I'm running a fairly dated computer: 6000+ dual core (2 x 3.0ghz) Asus Matrix 4850 512MB @ 725/2000 core/mem 2GB DDR2 800 Forget my motherboard model as I'm at work but it's an am2/am3 board. Just wondering what I should upgrade first to get the biggest bang/buck performance increase for BC2? I play on my 1920x1080 22" BenQ monitor and would like to play on at least medium settings. I have the game on order. Cheers.
