Intel doesn’t even try to hide the fact that it is very upset on Nvidia’s attitude. Nvidia simply doesn’t want to let Intel to use SLI on X38 or other 3 series of chipsets. Intel tried to win this one but Nvidia simply doesn’t want to hurt Drew Henry's chipset business and wants to remain exclusive on the SLI runs on Nvidia only side.
