Currently the GTX Titan and 700 series are the only video card that comes stock with a UEFI bios. If you own a 600 series kepler video card, GT640 and higher, please contact support@evga.com, include the serial number and make/model of your motherboard. The UEFI update doesn't contain any performance increases just support for the secure boot option within Windows 8 and a compatible motherboard.
