I have amd 5200+ and asus m2n68am mobo.. which i cannot upgrade at the moment. I have corsair 400w psu and 3gb ddr2 667 ram and a crt 17" monitor. suggest me a good graphic card which can run crysis, farcry2, mw2, and all the latest games. I am thinking of ati 4850. I dont have any graphic card right now .
As long as you have updated BIOS, your motherboard should be able to support the Athlon II and Phenom II dual cores(though I'm not sure about the quad cores).You can go for them if you feel that your current CPU might bottleneck the 4850.
