“With the PCI Express slot ready to go, you need to choose a card to go into it. After a few years of testing various cards, our little group has settled on Polaris generation AMD graphics cards.
Why? Because they're new enough to use the open source amdgpu driver in the Linux kernel, and old enough the drivers and card details are pretty well known.
We had some success with older cards using the radeon driver, but that driver is older and the hardware is a bit outdated for any practical use with a Pi.
Nvidia hardware is right out, since outside of community nouveau drivers, Nvidia provides little in the way of open source code for the parts of their drivers we need to fix any quirks with the card on the Pi's PCI Express bus.”
I mean in terms of his quest for GPU + ARM. He's been futzing around with Pis and external GPUs and the entire time you've been able to buy a variety of SBCs from nVidia with first class software support.

I’m not in a position to evaluate his statement vs yours, but he’s clearly thought about it.
