My little brother is really in need of a new computer. He is wanting to play games like Counter-Strike, HL, BF2, and all types of FPS. I have a few left over components that i can use but he still needs a processor, motherboard, ram, video card, cd drive, and maybe a PSU. He has a budget of around $500. I would really appreciate it if you guys could suggest something for him. Thanks a lot.
