Alright, he says he wants a 6600 vanilla .. but honestly I think this computer is unbalanced, unless you're looking to run the dual-core-supported apps of tomorrow or something. The 3800+ isn't going to know what to do with itself while it waits for the 6600 to catch up
eVGA GeForce 6600 Vanilla 256mb <- can a 6600 handle 256mb? if not go for the MSI 128mb one
3800+ X2 AMD CPU
antec truepowerii 550W
2gb corsair valueselect ddr400
asus a8n sli deluxe mobo
maxtor maxline iii 250gb sata hd (out of stock)
that stuff totals ~$1050 shipped including $100 for the maxtor when it's back in stock
windows xp pro ($75 from eDirectSoftware.com)
windows works suite 2005 ($50 from eDirectSoftware.com)
Plus that stuff makes $1175, so that leaves you $200 to pick a case, burner ($30-$40), floppy ($10), fans ($10 each?), nice cables, etc. Best of all, you get the fun of putting it together yourself and being proud of the result!
But that PC isn't worth having for $1300. The 6600 is a big bottleneck. My $800 comp (sig) is probably better for gaming .. no offense.
