Hi,

Can I use my GTX770-DC2OC-2GD5, currently running fine on Legacy BIOS in UEFI boot mode? I'll need to get Win 8.1 in UEFI, but I'm having image backup problems, and may at least need to do recovery...if not reinstall Win8 and upgrade (groan). But if I do have to I'd like to get the faster booting with UEFI.

Here is my computer's relevant Performance Test Information for the board:

Video BIOS: Version 80.4.c3.0.2
Driver Version: 9.18.13.3182
Driver Date: 11-11-2013

I've been updating from Nvidia as the control panel finds updates, but I can't use the Asus vBIOS update, as it says it doesn't support this card...which seems odd. Perhaps it's already updated?

The support page's sales blurb says it supports it, but there are no documents, manuals or FAQs for this card, so I can't tell if there's some procedure.

Thanks,

-Ambi

P.S. I have 3 RAIDs set up on the Intel controller. RAID-1 SSD for Win 8.1, RAID-0 SSD for temp / paging, & RAID-1 HDD for data. Will this be a problem for the MB in UEFI?
