Nvidia is pushing to sell its Nforce 200 chip to the motherboard vendors, but many have told us that Intel's reference design doesn't include support for Nvidia's SLI chip.

Intel wants to get the software support for SLI, and Nvidia insists on selling the Nforce 200 chip as a solution for SLI. This makes things awkward for motherboard manufacturers, as they are stuck in the middle of a nasty fight. The initial boards based on Intel’s X58 reference design won’t run SLI, they will run Crossfire; but motherboard manufacturers seem to have X58 boards with SLI Nforce 200 chip under design.

At this time there are no plans for Nvidia to make a Nehalem chipset and it doesn’t look that Intel is eager to share its Nehalem technology with Nvidia.
