so i just put together a budget x2 3600 build... here's a few things that i got:
x2 3600 with ecs mobo (combo on newegg) - 106
2gb corsair XMS 667mhz ram - 70
320gb sata 3.0 Maxtor hd - 64 (got it at a fry's though)
Ultra Micro fly MX6 case with 600W XVS PSU - 100ish (amazon.com, but i paid tax)
Sony DVD-RW - 32
the case/psu deal is great because i havent seen anything under 120 for that combo.
anyways, the total is about 375. pretty decent IMO
