Elmer, Re: I believe PCI-Express is 2.5Gbps which is 8b/10b encoded so the actual bandwidth is 2Gbps.

The PCI-Express clock runs at 250MHz. A single link, as you say, can deliver 2.5Gbps (or 2Gbps of raw data). However, PCI-Express is scalable to multiple links. If Intel wants to have an advantage over the current AGP 8x standard, they will need to use a x16 PCI-Express connection for 32Gbps, or 4GB/s of bandwidth.
