Re: Buying gaming system.
cant really say. prices will surely change between now and christmas time.
for a gaming rig though, i would say some minimal specs in your price range would probably be any of the athlon ii (duals, triple, and quad cores) or phenom ii ( most likely the duals and triples, quads would cost more) for cpus. and for gfx cards probably like a 4770, or any of the hd 48xx series cards. with 2 or 4gigs of either ddr2 800/1066 ram or ddr3 1333/1600 ram.
but again, im pretty sure prices will change but i guess something like those ^ could give you a ballpark idea, even if its a little vague >.<
