keep in mind that the 3870X2 has 2 GPUS on one PCB board.. which means it will use alot less power then the 9800GX2 which is 1 gpu on 1 PCB board.. and the GX2 is 2 PCB boards attached to each other and linked internally by a pcb bridge.. this design is inferior to the 3870X2 because the gpu- gpu link on the 3870X2 is much shorter and smaller therefore, faster and uses less watts to power.
