This Commando board in crossfire mode offers one slot at x16 and the other slot at x4. So if the above logic is correct, this board will not support the new ATI/AMD graphics cards in crossfire mode.

If I am not mistaken, even the RD600 chipset only offers 8x by 8x for crossfire mode. So it cannot use the new R600 graphics cards?
