Notice that between the x48-dq6 and the P5Q-D, theres 1.3fps difference in it...the same difference that was shown in the THG article over here:

See? Between 8x PCIe 2.0 (4GB/Sec) and 16x PCIe 2.0 (8GB/Sec), theres almost no difference.

And yes, the 9800GX2 reports the same non-difference as the Radeon 3850.
