P5W DH DELUXE only has 2 16x slots....
TRIPLE PLAY physics require 3 pci 16x slots (one of them runs 4x or 8x for the physx lane)
But see....crossfire physx only requires 2 cards. One of them focuses on graphics and the otherone focuses on physx.
Hope I helped you out.
Yes but wouldn't both PCIe run at 8x mod when crossfire enable?
