Sandy Bridge-E Users Beware of GTX 680 Drivers

So the NVIDIA GeFroce GTX 680 was released yesterday, and they were sold out almost immediately. If you were one of the fortunate ones who were able to get your hands on one as well as a Sandy Bridge-E X79 chipset user, you may want to hold off on downloading the newest available drivers.

On's specifications page for the card, they list it as a PCI Express 3.0 card, but they have some small-print that says on the X79 chipset it's limited to PCI Express 2.0 speeds:

 GeForce GTX 680 supports PCI Express 3.0. The Intel X79/SNB-E PCI Express 2.0 platform is only currently supported up to 5GT/s (PCIE 2.0) bus speeds even though some motherboard manufacturers have enabled higher 8GT/s speeds

There is some good news, though. According to TechPowerUp, the drivers that ship on the disk are the pre-launch drivers that will support PIC Express 3.0 on the X79 chipset. I know it's weird to use drivers off of a disk, but sometimes that's just what you have to do. NVIDIA should release an update some time soon that will fix this limitation and allow you to upgrade drivers.
