Pro GPU? - Gentoo (used) workstation build

[Zucca]

This is a bit like a continuation to my earlier topic of if I should choose dual CPU or not.

I chose to go with dual CPU. For the base, I bought a used Dell Precision Tower 7810.
This is good opportunity to learn the possible quirks of such system. I stuffed it with 8x32GB of RAM.
I also found a pair of Xeon E5-2697 V4s just for 70€ (about the same in USD). I'll install them later. It now has Xeon E5-2620v3s (Which I probably move to my server later... that's another story).

I plan to use at least two 4k displays with the workstation. I'll maybe add third display there (1600x1920).
I've been looking at used Radeon Pro GPUs, but also non-pro.

Now... If I buy, say Radeon W9100, will it work just fine with amdgpu drivers? Can I utilize GPGPU just like if it was a "consumer" GPU?

Any suggestions for a (better) gpu for my setup? PCIe in this workstation is 3.0 and the setup can generally accept a GPU of around 300W of power.
I don't want to fight with nvidia GPUs. I use wayland and it seems nvidia isn't there yet. I also don't like to use their closed source drivers. So the other ones would be Intel GPUs. But does my PCIe 3.0 bottleneck them?

Zucca,

Before your topic sinks to oblivion, I'll post what I know.

When I put together my bucket list PC at the end of 2021 I looked at second hand AMD Pro graphics cards.
Consumer graphics cards were like hens teeth and stupid prices at the time.
I was not considering a second hand consumer graphics card, as they tend to be thrashed within an inch of their lives by 'miners'.
In the end, I kept my old graphics card for a while.

None of the rest of this is tested.
My research suggested that the Pro cards use consumer GPUs. They are not supposed to support gaming. So that's OK.
The inference is that they will work with AMDGPU, but as I say, I did not put my money on that.

Some supporting cirumstantial evidence can be found on cateee.net

Thanks Neddy.
I already bought Radeon Pro 320V, which is a data center GPU, but it's also same as WX 8200, I believe.
The price was around 170€ with postage. It's pretty the same as WX 9100, but has half the VRAM - 8GB. I may regret this choice.
Oh well.. I can put it on my server if I were to buy WX 9100...

I'll update this topic when I have tested the GPU.
