I have recently stuck a 7950GX2 in my P5W DH Deluxe.
Everything is running fine, impressed with performance etc.
3DMark06 = 8260 (stock clocks)

However, I have noticed that the PCIe slot is running @ x8 rather than x16.
Is this normal? Will it effect performance? Can it be changed?

Maybe other people could check their systems and let me know....
(CPUZ, Rivatuner, Everest etc. can all be used to check)

I tried playing with the Asus PEG Link settings in the bios but could not get it to change
