Disclaimer: As best I understand it. There's been a number of claims put out, but this seems to be the most reliable one. There seems to be a little term-fudging as well, as the lanes provided by the PCH are apparently "PCI-E 2.0 compatible", but they actually only run at first-gen speed. So you can plug a 2.0-spec device into them, but it's only going to get 1.1-spec bandwidth. Perhaps that's not an issue with PhysX, but it helps explain why Nvidia won't support Tri-SLI on triple-slot P55 motherboards, just SLI+PhysX.
