GeForce 9800 GX2
The dual GPU GeForce 9800 GX2 card requires at least x8 PCI Express 2.0 to deliver high frame rates. Going to x4 link mode clearly bottlenecks the graphics flagship.
Crysis shows a noticeable impact when running on a reduced number of PCI Express 2.0 lanes, but only at very high quality. It’s amazing to see that you’ll get almost full performance even at x4 link mode.
These results confirm what we already saw on the ATI Radeon HD3850 card: Flight Simulator X heavily depends on PCI Express bandwidth. Reducing the x16 PCI Express 2.0 links to slower ones noticeably bottlenecks the simulator, as access to textures stored in the system main memory becomes far too slow.

The x1 mark is wrong in the diagram- it's the gap right after the key, not ON the key!
My nVidia GeForce 8800 GTS 512 is marketed as being PCIe 2.0. Why is this not listed?
Typo on the last page referring to 9800GX2 as 9900.
My nVidia GeForce 8800GS 384MB is marketed as being PCIe 2.0. Why is this not listed?
This article is terribly misleading and does not test what it promises. It's only purpose is to test PCIe 2.0 x16 against PCIe 2.0 x8, x4 and x1.
Woulda been nice if they actually tested PCIe 2.0 (x16) against PCIe 1.1 since this would actually be of some relevance and importance to us. Anyone else think so?

I agree
