get a core 2 duo, E6400 or something, maybe a 7600gt, or 7800gt. OR get a cheap crapo card now, wait til about easter when the 7 series goes down, and the cheaper 8 series comes out. I saw a couple places that had a 19" lcd on sale for $99 And bestbuy had a 22" widescreen for $199. But most of the black friday deals are goin to be over soon. Get a 600W power supply for future upgrades. Always think ahead.
Hope this helped a bit. Always look at ebay, a lot of computer stuff is new there.
