You're going to be hard pressed to find a "gaming" laptop cheaper than the MSI EX630-034US ndatoxicity posted up. That's a great price for the amount of options it has.
u can always go look at a dell, acer, or toshiba website and look up the hardware specs.... if u find one with the right price, post the specs and we will tell you
if you want gaming, look for a laptop without integrated graphics (like intel GMA - graphics media accelerator... a really crappy video card integrated into the motherboard)
