New Mac Pro with nVidia cards / Catalina?

Hi,

I have a not directly egpu question, but figured you guys would be the most knowledgable regardless. Looking through forums I couldn't figure out definitively an answer.

I'm thinking about buying a new mac pro, using the AMD card as main GPU. However, I do alot of rendering using nvidia iray, which uses cuda, and apparently is unsupported in catalina. If it's possible, I'd like to add a pair of 2080 ti's, for the purposes of iray rendering, directly to the mac pro. -- I'm currently using a bizon box (on my non catalina imac), so I've had to use the purge wrangler script for that, and a couple of posts gave me hope that although it's not directly supported by catalina, that using the purgewrangler script it may be possible?

Anyone happen to know for sure whether it's possible to use cuda in Catalina using a workaround script?

I would like to see links to those posts that gave you the idea that Nvidia could work in macOS. Or are you going to use them in Windows/Boot Camp?

Mac mini (2018), Mac Pro (Early 2008), MacBook Pro (Retina, 15-inch, Mid 2015), GA-Z170X-Gaming 7, Sapphire Pulse Radeon RX 580 8GB GDDR5, Sonnet Echo Express III-D, Trebleet Thunderbolt 3 to NVMe M.2 case

I'm hoping to be able to use them without using bootcamp. After further reading the posts I was looking at, I may have missed some things, TBH, the more I read the more confused I get about compatibility. 🙂 Maybe because the general context is egpu and I'm not sure if all those same restrictions apply if they are connected directly in the mac pro via pci or whatever. Obviously, I'd need working drivers though.

Things I'm still confused about:

As far as I understand the breaking version is anything > High Sierra (where the drivers no longer exist). But several posts seem to be saying specific cards and or older nvidia cards, i.e. GTX 7.X series, will work with Mojave. So in theory shouldn't they work with Catalina as well?

TL;DR; Basically, I'm just trying to figure out if there is any hope for any nvidia cards in a mac pro natively (I'm not using to power displays either, just for the cuda rendering functionality, not sure if that matters or not). I'd gladly sell my 980 and buy 780s, or Titan Z's, or whatever, if it's possible to use it in the new mac pro.

You might not have CUDA support as the toolkit was never released for Mojave/Catalina, so while the Kepler GPUs might work, it would be a fruitless exercise. It might be easier for you to have a modern NVIDIA GPU instead for bootcamp use.
