You can get SLI to work, but it isn't "supported". The black slot does not have as much bandwidth as the blue slot. That's about as cut and dry as it gets.

why do they state the board has dual 16x PCI-E and not 16x & a 4x

Technically, they both are PCI Express x16 slots. The one slot just doesn't have the full amount of communication with the chipset. It has the same bandwidth to it that a 4x slot technically would have, but it's physically x16 to make sure all the modern graphics cards fit.

Not sure, but the chipset is what causes the bandwidth restriction, the slot itself is still x16 compatible (physically).

EDIT: ^^ What he said ^^

so theres no point at all using this board for SLI or CrossFire the black slot will restrict the badwidth

Right, but it will still improve the performance, but not on 8800 cards too much. On say an old 6800 SLI setup, there wouldn't be enough data rate to restrict, so it would be worth it.
