Do you need printer/monitor/keyboard/speakres/mouse?
I would go for the MSI NEo 4 board for around $80 at newegg.com. Upgrade to the AMD 64 X2 3800+ or you could stick with what you have now, if you cannot afford to. Get the pci-express Leadtek 6800Gt or if budget allows evga 7800GT for $400. NEC-35420A Black IDE DL DVD+_BURNER. I would go for 2 SATA 3.0 160GB, each $80= 2x80=160. Corsair XMS ram is not needed. Suggest the Geil sticks that are around $90. Don't forget windows and arctic silver 5 if needed. You are also leaving out a case and case fans.
