Default Running ATI CF @ x16 x16 w/ 1156 mobo

As title states, I am wondering if there is any such 1156 (i5) intel motherboard that will run two 4890's in CF at the full x16 for each physical pci slot.

Also, if it is true that there is no such mobo then how much performance decrease am I looking at if i run the CF setup with;

#1 - x16 main physical pci slot AND the other physical pci slot running at x8
or
#2 - both physical pci slots running at x8

Any links to guides, benchies (official or non), reviews etc which may lead to further insight/research are much appreciated.

Thanks.

Ok so then just the second question applies now, which is how much perf decrease I will potentially experience.

Thanks.

@atennisplayah
