Depends on what OS you want to run.
For the 5,1 Mac Pro
If you are running Monterey and don't want to do the Pixlas Mod then AMD Radeon RX6800 flashed for Mac
If you are willing to do the Pixlas Mod then the RX6800XT flashed for Mac
Now here is the stupid part if you need to upgrade even temporarily to Sequoia, in my case to run DFU for an upgrade on a Mac Mini M4 then you will need to downgrade your video card.
I had to put back in a GTX680 to be able to upgrade a drive to Sequoia
Yeah I know backwards right because anything after Monterey doesn't support AMD Radeon GPU
So if you are wanting run Sequoia and not do a Pixlas Mod definitely a RX580

Mac Pro 5.1 graphics card --high sierra compatible--... suggestions por favor.

Running dual display in recording studio. One of my monitors stopped working (OG card) after cable swaps the monitor is fine so must be the OG graphics card.

Ordered this RX-580 but it's back ordered so ? who knows when will get here.

Also ordered this RX-560 and it arrived but seems to have no 8 (or 6) pin graphics card cable so?

Just need a solid option which I'm told is the RX-580 but, there seems to be knock offs and not sure what's what.
Thanks!

I had a Sapphire 580 in my 5,1 for a couple years then it died. Replaced it with a 560, and it's still going 5 years later.

I don't do anything GPU intensive just audio.

Not even macOS compatible.

RX580 2048 SPs are fake cards made for the chinese market. Real RX 580 have 2304 SPs (StreamProcessors/CUs).

Manufacturers get 2nd hand RX 570 chips removed from abused crypto mining GPUs and then make a fake RX 580 with a new PCB. The fake have a different PCIe ID from the real one.

Apple AMD drivers does not work with these 2048 SPs GPUs.

Also ordered this RX-560 and it arrived but seems to have no 8 (or 6) pin graphics card cable so?

This is also suspect, since a real RX 560 have 1024SPs and these one is 896SPs. Never got a RX 560 896SPs, so I can't say if the Apple AMD drivers work or not with this one.

Some RX 560 models do not require additional power, the power is fully drawn from the PCIe slot.
I personally don't really like to use the PCIe slot power to the limit like this GPUs does, but maybe works fine for your workflow.

Thanks!

On the cheap, your best bet is 2nd GPUs sourced locally, a real RX 580 with 2304SPs.

If you can't find one, maybe try one of the AMD Pro cards, like the AMD Radeon Pro WX 7100 that is the Radeon Pro equivalent of the standard RX 580 2304 SPs.

Buying these directly from AMD store have no chance of fakes, have full warranty, require one PCIe slot only, are very cool/silent GPUs and require just one 6-pin power connector.


These Radeon Pro GPUs like the WX 7100 are very sought after for studio usage, cool, almost completely silent, one PCIe slot only.

Expensive? Yep, but you have what you pay.

Well that's good to know. I'll be returning it.

I think the WX 7100 sounds like it's worth the few extra bucks. Thanks much for these insights! Really helpful.

fwiw possibly to others, OWC has this 5.1 compatible card as well...

I personally ordered, and waiting for the WX 7100 to arrive.

Does not make any sense to pay OWC prices for 2nd hand RX 580 GPUs when you can buy from the AMD store the brand new Radeon Pro WX7100 for just $30 more.
 
Since FirePros are same arch as RX580, they work past Monterey on cMP5,1 , correct?

FirePro WX 7100 is also an Ellesmere based GPU, so, the same compatibility and limitations as a the consumer RX 480/580 GPUs apply - AMD used the same chip/almost the same clocks as the RX 480.

Being very pedantic, the WX 7100 is the professional version of Polaris 10 XT initially released with the RX 480, AMD did a better bin process of the Polaris 10 XT and the binned version was renamed as Polaris 10 XT GL. This was done to have the cooler and lower energy consumption chips, so the GPU could be 1-slot only. In the end, the best Ellesmere chips were reserved for the FirePro GPUs.

For the RX 580 GPUs, AMD used a re-spin of the same Ellesmere chip. This one achieved bigger clocks, but with a substantial increase in power draw and working temperatures. This re-spin version of the Ellesmere/Polaris 10 XT was renamed as Polaris 20.

Would it generally Not be advisable to buy a used WX 7100 VS a new one?

Point being, the new one I ordered is taking freaking forever from Amazon. Will be at least another week, maybe more. I was considering grabbing a used one that will get here in a few days & is cheaper of course. But maybe I should just wait if it's risky w the used not knowing how much use it's seen.

You will be Very happy with that WX 7100 card. Unfortunately the Professional GPU line from AMD gets not enough media coverage. They usually run cooler, have better engineered cooling and also better driver package on the Windows side. I am super happy with my blue workstation card.
However, since I upgraded mine, for everybody who needs a really good 8GM RX580 Pulse for the MP5.1 (Mac EFI) with upgraded cooling, I still have one for sale.
