I just recently switched from console gaming and finally built what I think to be a decent PC. And I plan on picking up Arma2 and definitely Arma3 when it is released. I just wanted to know with these specs would I be able to run arma2 at decent settings. I'm also assuming I should change the gpu for Arma3, right? -Specs Cpu: i5 2500k Gpu: gtx 650 ti ssd: intel 64gb hdd: wd blue 500gb 7200rpm Psu: Rosewill 650w Mobo: Asus p8z77 Much thanks in advance.
