will call of duty 4 work on nvidia geforce 7600 gt 256 mb pci-e graphics card,i have geforce 5500 doesnt work?

Answer 1

FX5500 is a slow AGP card that only supports Shader 2.0. It does not meet the requirements of the game.

7600GT PCIe is faster but will not be compatible with your AGP slot. Get the AGP version.

If you want awesome performance, get these:
-ATI X1950 Pro AGP
-Geforce 7950GT AGP
-ATI X1950 XT AGP
