Hey i got this mobo im about to order and it is the Asus P5Q pro, P45 chipset. I know when running crossfire on it each PCI E slot X16 is running at X8. Quick question if im only running 1 graphics card is that one card running at full X16 rather than X8.

Yes.
As long as your single card is running in the top PCIe 16x slot, it will be running at full speed.

The blue slot is the one you want.

And if you add a second card, the drop to x8+x8 won't hurt that much. It's only important IMO at 1920x1200 or more, from what benchmarks I've seen.

wait, if you use one card does it matter what pci x16 slot you put it in?

Yes it does.

here is a quote from ASUS specifications

"2 x PCI Express 2.0 x16 slots, support ATI CrossFireX™ technology at x8 link
(PCIe x16_1 blue, PCIe x16_2 black*)
1 x PCI Express x16 slot at max. x4 link(black)"

So unless in crossfire mode the black will run at 4X and the blue will run at 16X
