Hmmm, i didnt try the gtx 680. But ... it should work.
I own a flashed gtx 980 ti in my mp 2010/5.1, this one works perfect.
Unflashed grafic cards for windows systems should work, but they dont show the booting screens, until osx has fully loaded. So in case of booting problems you will not see any error screens, and the osx boot volume selection screen (where you choose between osx and boot camp) cannot be displayed.
Flashed grafic cards will show you the boot screens too.
Have a look at http://www.macvidcards.com/, they have a wide variety of grafic cards, from low cost up to high end. And they have a flashing service for many pc cards.

Ok just to confirm, MacPro here with Crucial 500GB SSD and NVidia GTX 680 2GB card installed. Runs Mojave well.
Did you do all the pre install checks.
Make a full back up of your Mac first. Use Disk Utility> First Aid to check for errors. If errors are found you will need to boot to your Recovery HD and run Disk Utility> First Aid until no errors are found. Is there plenty of free space on the drive, at least 20GBs.
Open System Preferences> Users & Groups> Login Items, if there are any third party apps in the login items highlight them and click the minus sign to remove them.

If still having problems boot to Safe mode and try installing from there, Use safe mode to isolate issues with your Mac - Apple Support
Make sure your Mac High Sierra installation has all the necessary updates installed prior to trying the Mojave install.
Has your Mac been running fine on High Sierra, if not is better to resolve the problem first before upgrading.
