NICE!
Very sweet setup there.

Here we can see one of the differences between the P8P67 Deluxe and the P8P67. The P8P67 only has two PCIe x16 expansion slots. The second of the PCIe x16 slots defaults to an x1 slot and must be adjusted to x4 in the BIOS to support AMD CrossfireX. Doing this does come at a cost, though, since the ASUS P8P67 doesn't have the added PCIe lanes that the PLX chip provides on the ASUS P8P67 Deluxe. Once the second PCIe x16 slot is enabled to x4 (default x1) both PCIe x1's and USB3 three and four (front panel USB3) will be disabled.
