I recently purchased a Flashed Nvidia GTX680 Video Card for my Mac Pro 5,1 12-core. Card works fine but after updating to Mojave OS I find out there is no update software available from Nvidia for the card to be able to utilize the GPU acceleration built in. Nvidia and Apple are both aware of this and both say updates are coming shortly. In the meantime I basically have a glorified 5770 that can't do anything I purchased it for other than the fact that it is at least compatible to run with Mojave OS.
What is All Macintosh Roms (68K + PPC)? This is an archive containing all of the most popular Macintosh models ROM files for emulation purposes, ranging from the first 64K ROM from the Mac 128K to the 4MB ROM files from the Bandai Pippin or PowerMac G3, listed below in ROM size, then by release date from oldest to newest.
Feb 17, 2019 While the 680 and 770 are based on same basic core, by the time the board partners made the 770 they all went in their own direction with components. Most notably the VRAM, fan(s) and power management varied from card to card. In comparison, most 680 cards, expecially the 2GB ones, used similar parts, hence the ability to use the 'Mac rom' on.

Jan 08, 2013 The rom is indeed one released by MSI for a 2gb reference GTX680. The fact that card functions perfectly as PC Card once flashed shows the GOP thing is problem. Google UGA GOP UEFI and you will better understand problem. Basically, Mac Pro is only Mac using UGA. I have extracted EFI from iMac 2012 and rMBp, they are also GOP. GTX680 Or Sapphire 7950?

Make sure to install Latest Nvidia Web Driver before updating to Mojave. This is very important as it is not easy to code it in after the fact. The 680 card will function fine and hopefully they will release the software update soon (Even though the rumor is that Nvidia has already supplied the update to Apple and they are holding on to it for whatever reason)
Mac Pro, macOS Mojave (10.14)
