I read several reviews on newegg stating that enabling usb 3/0 / sata III degrades the PCI-e to 8x, but looking at the manual it says the PCI-e goes to 8x if you enable "IO Level Up". Can someone clear this up for me?

If it is true that the PCI-e card goes to 8x only if you "level up", what is the USB 3.0 rate with out the IO Level Up?

One more question...
Can I use a Sata 6 gb/s cable for a Sata 3 gb/s device?

I think so, I have the same board, I disabled IO level in the Bios, Now I am not sure if without the IOlevel up selected , you can use sata 6 or usb 3.0.. not sure if they perform faster than 3.0 or 2.0 for usb..
