Where are y'all getting the hard facts on the 4870 / 4870X2 from? Is this shared memory rumor still going around I'd like to know the 'multiple' reasons that the X2 will end up faster than 2 4870's in CF, all reasonable expectation and past experience (3870X2) says the opposite.

Yeah, though unless DAAMIT have managed to overcome a basic limitation of these solutions you will still have 512mb of usable memory (frame buffer) on the crossfire setup, and also half the bus width of the 280.
