It has 4 slots: the first three are x16, and the last is x4, so I doubt that's the problem. Also, the problem is most likely much greater than a simple fix. His 2 GTX 560ti's perform worse than my single GTX 560ti did, I can almost guaranty that something is either broken or seriously wrong with his computer. However, I really have no clue why it would be under-performing like this. Does your computer crash often or come up with any other errors or problems than just under-performing?
EDIT: Man, that's a nice motherboard, I want an Intel version of that!
EDIT2: Hm... Try updating your bios, there might be a weird glitch where the PCI-e slots are under-performing. I've never heard of it before, but it might be possible that all the PCI-e slots are all seen as x4 to the computer because of a glitch in the bios and the bandwidth is limited by that.
