I will give you almost a whole PC for $260 including shipping as a combo.
GPU: GT 240 1 GB -Will not sell alone - Not the most powerful, but better than a A8 by at least 15 percent.
Motherboard + CPU + Stock Intel cooler + RAM: Evga 650i, c2d e4300, and stock intel cooler. The motherboard is evga, so that means=Awesome, and the cpu isn't the best, around a4, but still enough for a powerful HTPC. 533 mhz dual channel 2 x 2 = $130 including shipping
PSU: Seasonic 380w. Pretty silent. Great brand, above corsair cx quality, and above gs, and a whole lot quieter than those whining cx 430 an cx 500. Will not sell alone.
