Re: 8800gts ~ $80
yeah i remember paying $275 for my 512mb 8800gts. too bad it broke and the shipping got messed up when i RMA'd it so im not getting it back. anyways, i knew someone who had an 8800gtx and my 512mb performed slightly better. im sure the 320mb gts is a step up from an 8600 but you may want to save a bit more and get a card with a newer core.
