Just wondering if someone can clarify the PCIe lanes on the ASUS P5Q Deluxe, sorry if its already been answered before but not sure what to search for:

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)
2 x PCI Express x1 slots
2 x PCI slots
*PCI Express x16_2 slot (black at max. x8 link)

I'm running a single graphics card, 8800gt, running at x16. I want to get a PCIE raid card (Areca 1210) which is a PCIE x8 card so I'm confused as to whether it'll have any affect on the graphics card. If I plug it into the first black PCIE slot will the card run at x8 and will the graphics card slow down to x8 or still run at x16?

1 x PCI Express x16 slot at max. x4 link(black) - is this the second black PCIE slot? And if I plugged the raid card into that would it run at x4?

Cheers!
