I bought this specific (asrock fm2a75 pro 4) motherboard earlier this year with the idea that I was going to crossfire a pair of AMD cards. Specifically I was going to crossfire two R9 270X and call it a day. That was until I was looking at the specs of my motherboard and apparently this motherboards second pcie x16 slot runs only at x4. This motherboard says its ready for quad crossfire. WHAT THE HELL? Am I missing something. How can a mobo be quad crossfire ready and only have 1 true x16 pci slot?

The fact of the matter is the mobo has 2 x16 slots. One of which is utterly useless in a crossfire scenario which contradicts the fact that it can crossfire in the first place.

Considering the fact that you still have to power that second card for that 1/4 functionality I'm going to call it 100% useless.
