the 3870X2 will be two GPUs on a single PCB, they did it not long ago with there X1600 GPU with a card called 'gemini' wasn't too bad really, AMD will have to price the 3870X2 lower than the 8800GTX/ultra to be competative, though i would imagine it would beat both the GTX and ultra one on one, plus 3870s overclock like mad and come with unreal memory speeds, should be a winner for AMD
