CoD 4 for PC Installing troubles

[Game4life]

I Recently bought CoD 4 for PC and whenever i start it says my computer doesnt have the right video card and so i was wondering what is the cheapest one i can buy that will work for CoD 4?

What are your currents specifications? What kind of expansions slots do you have? AGP? PCI? PCIe?
This is about as cheap as you can get:
Newegg.com - SAPPHIRE 1012 Radeon HD 2400PRO 256MB(128MB on board) 64-bit GDDR2 PCI Express x16 HDCP Ready CrossFire Supported Video Card - Desktop Graphics / Video Cards

i have no clue im only 13 so i dont know barely anything about computers or i would of figured it out but it says i need a better video card so ill probably just go buy one since my video card sucks any way

You can dowload and run PC Wizard, and that will tell you what kind of expansion slots you have. Chances are if you go out and buy a random card, it's not gonna be the right kind of slot, or your Power Supply isn't going to handle the upgrade.
It's best to know what your getting into before you go out and buy anything..
