PCI Express 8x vs 16x

[stoutpuppy1]

Well with the whole deal about the ASUS nforce boards having mislabeled SLI doodads, I check my nvidia driver details and it says im running PCI-E 8x, is there a big [performance] difference between the two?

Highly unlikely. Current high-end card are not even saturating the 8x AGP bus, much less an 8x PCIe.
