Budget "gaming" PC

[zaiin10]

I am new to building computers, And I am looking to build a budget PC that can play games like COD 4, MW2 ect.. on medium to high setting. I want to keep a budget of around 300 dollars. Could you guys help me out with any ideas on a build?

Thanks,
Nathanial

You could take the $500 system builder marathon build, and get a cheaper GPU, perhaps a Nvidia GTS 450 or a Radeon HD 6670.
