Should be no difference than current situation. The card can work in 10.14, no official support, no boot screen. But work as expected. Which means most of the current GPU options.

So what’s the cheapest graphics card for Mojave on a 5,1?

From MacOS and from Windows (with the Boot Camp program installed) you can change the startup disk before rebooting. I don't know, maybe there are other ways but that's how I understood how to do it.
Has anyone tried a Radeon R7 450? It looks like it might be a nice AMD alternative to a Nvidia GT 630 / 640. It has device ID 682B, which is contained in the AMD7000Controller.kext, so it is theoretically compatible. It's a Cape Verde Pro GPU like the HD 7750, so could we add the EFI driver to it?

[doublepost=1528315028][/doublepost]Does the HD 7750 work on HS? I found this post: #10. It leads me to believe a flashed HD 7750 works (but unflashed doesn't without a kext mod?).
If that's true, there are quite a cheap single slot 7750 cards. Also found out, only a single displayport would work on a flashed 7750, but that would be fine if it's just a bootscreen card.

Perfect ‘explainer’ - thanks.

Thanks for this. Will keep the stock 5770 and probably get a non-flashed MSI GT 1030 2GB locally for about $135 CAD. “Cheapest” in-store would be a Zotac GT 710 for $60.
Could I keep ‘em both installed, then just plug my monitor into the GT 1030 if I need the boot screen?
An AMD card like a Sapphire Pulse RX 560 would be better if you wanted to try Mojave before the final release.
The biggest problem I'm sitting with is power cables. I'm looking at that specific card, and it requires a 6 pin power connection.
Now with my HD5870 already using both the 6pins, I will have to start modding either the PSU or do a SATA to 6 Pin.
I suppose you could try a Sapphire Pulse RX 550. I don't know if anyone has tried one yet. Other RX 550s don't work, but the Pulse has the correct device ID that's contained in the driver so it should. The WX 4100 is confirmed to work, so that would be a safe option. A WX 5100 would work too and would be one of the fastest cards that is slot powered only.
Thanks, really can't justify paying a high premium for a slot only powered card. The RX 560 with some kind of power mod will still be considerably cheaper than above mentioned cards.
I'm just doing coding my machine, so don't need a massive amount of GPU horsepower.
Suppose it's time to face reality. If Apple doesn't do something for the stock 5.1 cards for Mojave, it's probably time to move on to Linux.
I noticed when I started with my original drive that I had set it up as an encrypted HFS volume and the Mac Pro was giving me trouble providing a boot screen due to my screen resolution. When I switched to my SSD I formatted as APFS and then encrypted via filevault in preferences and it now has no trouble providing a boot screen in 3440x1440. Also it doesn't ask for my disk password, it uses the user login and passes that onto the system. I guess what I'm saying is that I'm wondering if this will also bypass the need for an EFI card to boot encrypted disks.
It sounds like a good option for you would be to replace your HD 5870 with a Mac edition (or flashed pc) HD 7950 or GTX 680. If you Boot Camp, the Nvidia card looks like it may be a better option since the 7950’s EFI rom can’t boot Windows and needs the bios switched which is kind of an annoyance. It looks like macOS has native drivers for the 680.

I picked up a $100 nvidia card from macvidcards for my 5,1 because the GT120 doesn't support metal. Would it still show the filevault screen under mojave? Beats me, and $100 is small change to keep my 5,1. Its already got like 7 drives, usb 3, and an extra sata card.
For some, this might be a useful graphics card reference list comparing generations of Nvidia and Radeon: https://www.tomshardware.com/reviews/gpu-hierarchy,4388.html
Helpful if you got a stock card with your cMP and never did much with it and want to upgrade in future for Mohave.
These are non-flashed and don’t specifically list metal 2.0 compatibility, but from reading these boards I gather that you could start somewhere around a GTX 680 / HD 7990 / R9 280X for basic use and go up from there.

I'm missing all Maxwell cards in the list: e.g. GTX 980 Ti is as fast as GTX 1070.
