The blues are dedicated x16, the blacks run at x8 max. The blues throttle to x8 when you have 3 or more cards installed in order of installation (in other words, slot 1 goes to x8 when a card is installed in slot 2, its partner, but slot 3 stays at x16) I run 3 4850s in tri crossfire, and thats how the board sets itself up.

But it doesn't matter as far as we can all tell. x8 @ PCIe 2.0 has GOBs of bandwidth, so no issues. It seems that with the exception of the monster 4870X2, X8 or x16 simply doesn't matter.
