i am currebtly playing WoW, and my computer is a piece, to say the least. it sn't that good, and i frequently have freeze-ups. i only have 512 mb of RAM, so, what should i get to boost that to 1 gb?

i dunno, because i am a noob, as previously stated.

also any gaming computers that boast this that are 500-800 US dollars i am interested in hearing about.
