To flash it is not that tough, it is quite simple.
Step 1) Going to need a flash drive USB- DONT USE A FLOPPY to unstable and diffently dont want that flashing a vga bios lol.
Step2) follow the USB flash drive setup for the BIOS flashing of the motherboards. There is a link right from the 758 bios page. Dont put the motherboard stuff on it though. The AWD dont need and the mobo bios of course don't need. You just want the drive to boot to dos thats it.
Step3) download the latest Nvflash program. You can find the latest downloads from techpowerup website. MAKE SURE to make a copy of your old bios using GPU-z.
Step4) Put Nvflash and the new bios + THE OLD BIOS onto the flash drive. Write down both bios file names your going to need to know them later. Also make sure the file is a .rom and not a .bin. Nvflash will only accept .rom files. To change it just simply rename the file with .rom at the end.
Step5) also going to need some support files for nvflash. Their called CWSDPMI, CWSDPR0, CWSPARAM. You can yahoo them and find the download for them. My download was CSDPMI4B which contained all three in a bin folder. You need to put CWSDPMI, CWSDPR0, CWSPARAM onto the USB drive with nvflash. If you don't Nvflash won't run and will kick you out back to DOS.
Step6) Set the motherboard bios to boot off the USB.
Step7) You should see a dos screen. /nvflash -4 -5 -6 (The new bios file name you wrote down). It will ask to confirm with you, just hit y and y. The flash will take about 15-30 seconds and done. If something should go wrong and you get a black screen, dont panic!! Just type /nvflash -4 -5 -6 (old bios file name). That will flash it back to the orginal bios, it's called blind flashing. It also helps to have a second video card just in case this happens still can see a screen.
IMPORTANT!! IF you have two cards installed then you need to use a different command line. --index=0 is the top VGA card --index=1 is the bottom VGA card. So for two cards; flashing the top card will look like this /nvflash --index=0 -4 -5 -6 (new bios file name). The bottom card will look like /nvflash --index=1 -4 -5 -6 (new bios file name).
Step8) reboot and go into GPU-z. Check to make sure the bios number is correct. IT should be changed now to .82.
Thats it =D. Very simple, just like flashing a motherboard.
