A new BIOS update F62 has been done for the GV-R797TO-3GB graphics card.
But it's only for the PCB ver 2.1 (I think you should write it on the website).
Can you provide a BIOS with the new features (UEFI BIOS + new FAN curve profile e.g. 25% Fan Speed @ Idle) for those who have the PCB ver 1.0?
These UEFI BIOS is pretty important in order to activate Windows 8 Secure Boot.
I've contacted the support, but it responded me with a very bad french and something like "wait & see what will happened".
