Quite possible, as the date is March, and 4-way SLI is being released then. Or it could simply be the 7900?
I can already hear the annoying whirrrrr of those four fans and its making me ill. If they want 4 graphics cards they need to make a better cooling solution, preferably with one big fan. Also: It couldent be the 7900 as the flash shows "CPU, GPU" and then the mystery product. And as godlike as the 7900 will be when its released, its still a GPU.
What essentially amounts to the same ad is already showing up in the bit-tech ads, with a swirling atom logo for the third thing. If this isnt physics, Ill eat a big sheet o' cardboard
