GeForce GTX 680 supports PCI Express 3.0. It operates properly within the SIG PCI Express Specification and has been validated on multiple upcoming PCI Express 3.0 platforms.
Some motherboard manufacturers have released updated BIOS to enable the Intel
X79 motherboard and Sandy Bridge-E processor PCI Express 2.0 platform to run at up to
8GT/s bus speeds. NVIDIA is currently working to validate
X79/SNB-E with
GTX 680 at these speeds with the goal of enabling
8GT/s via a future software update.
Until this validation is complete, the
GTX 680 will operate at
PCIE 2.0 speeds on
X79/
SNB-E-based motherboards with the latest web drivers.
