GPU-Z tells me "BIOS reading isn't supported on this device", I'm going to try nvflash and see if that'll work.
E: nvflash says a driver error occurs, and I have a feeling it's because I've updated to stock Nvidia 304.79 drivers.
I don't know if I can be bothered rolling back to the ASUS ones just for this..
Anyway doing what he wants you to is very easy:
Downlaod this:
http://www.techpowerup.com/downloads/2154/TechPowerUp_GPU-Z_v0.6.3_w_ASUS_ROG_Skin.htmlLaunch it, and when it asks whether to just launch once or install, pick the one you want
Once in the program, next to the "BIOS Version" box, there's a small icon, click it and select save to file.
Voila
Edit 2: I attached a screenshot of my GPU-Z, see if that's worth anything to him.
