well, if i was in your shoes, i would buy a 680i sli mobo and a q6600. buy at least 2 gigs of ram(you will want ddr2 or better) and a nice at least 7200 rpm(size matters on what games you are going to play) hdd with a dvd rom drive. next for the graphics card, the 8600 gt xxx is a good budget card for gaming(i have it and over clocks well).
haha sorry for the long post
does that help?
