I understand this, but can this happen on ONLY one of the two cards inside a single Mac.

My understanding is that he has a Mac.

There are two 1080s inside this single Mac.

One of the 1080 works fine, but the other is not.

So, this can happen on only one of the two cards in the same Mac?

Applications that have Library Validation enabled, like the Window Server, will not load the driver for either card.  Applications that don't have Library Validation enabled will work fine.  The solid dock (and general UI stuttering/lag) is the classic sign that you have LV issues, even if CUDA or other non-Apple apps appear to be working fine.

That means the EFI part needs to start directly at that point.

Open the 7970 Mac file in a Hexeditor.

At 65536 you will find the EFI part.

Copy and paste into your R9 280X at same point, overwriting the UEFI, done.

For the Powercolor R9 280X (which works fine in High Sierra on a real MP5,1  the EFI part of the BIOS starts at 65412, not 65536.

What do I need to do to compensate for this?  My previous MSI card was pretty straightforward.

My original ROM attached...  Any help appreciated.

The gaming consoles' optimisation, stability, cost to performance ratio, or even the cooling system... are so much better than the current generation Mac  Grin

I was aiming at, "I need CUDA in macOS and what are my options since 2013 iMac (GTX780m) until today" scenario, but couldn't agree more.

Apple acts like it is a gaming console maker and see no need to offer both AMD and Nvidia as an option.

Again, how do you know that?
For all we know, nVidia could fix these issues themselves. People don't blame Microsoft when some GPU driver has issues. Ok, ok, they did when Vista came out, but apparently it was also mostly nVidia's fault.
We can already consider ourselves lucky that nVidia releases drivers for cards that never shipped with Macs. And eGPU on macOS is only experimental at this point.
I don't think nVidia is putting so many ressources into the optimisation of the macOS web drivers. It's probably low priority for them.
Have you ever seen Windows Defender (or MSE, depending on Win version) blocking AMD or nVidia driver in the middle of the installation?

I'm not in disagreement with you, i'm sure nvidia is having only one or two guys in the basement as part of Mac team, but macOS isn't getting less hostile to the WebDrivers as the updates are coming.

Agree that we're lucky that Nvidia is giving us drivers for all the cards, but that is another thing in which Apple acts like it is a gaming console maker and see no need to offer both AMD and Nvidia as an option. Especially as they offer such a different functionality and macOS supporting Apps that are still much stronger and more optimized in CUDA comp.

Not toolbar.  Solid white dock.

This means Library Validation is getting in the way, as has been discussed at length.  Not the driver's fault.
