best gaming computer

[yamahauler]

i need a good gaming computer that can handle some pretty big games like counter strike and warrock. it needs to be under $600. it doesnt even need to be a gaming computer it just needs to be a good computer that can play games.
if you have a computer that can handle some big games, give me a link or a picture.
