Does anyone know of any professional cards that within a reasonable budget that I could use between a few VM’s?
My end goal is to share it between my jellyfin vm for better hardware transcoding and my f@h for better gpu compute.
It would need to be limited to 1 slot in thickness due to it going into the 1U server ( ProLiant DL325 Gen10). I might be able to get away with a 2 slot but it would be choked.
I’m trying to steer towards the low end of things because there are no dedicated power cables besides the pice slot.
Or would it be better to get a thunderbolt dock as pass that through to the VM?

That’s nice but the power draw seems to be too high. I’m capped at the output of a single pcie slot so limit is 75 W
I was watching one of these on ebay and it went for £60. Box and unused;
AMD FirePro S9050 12GB Professional Workstation Server GPU Graphics Video Card
Note the S in it’s name, it’s for Server. The Workstation ones begin with W and can’t do what this does.
I don’t think it’s super powerful, probably like an HD 5970 but with massive RAM. The special thing is it does SR-IOV to allow it to be shared with several VMs as the graphics card.
I was considering putting it in my Proxmox but in the end I put a normal Radeon in and used IOMMU.
I would do this but I can only fit 1 GPU. Currently, have at least 2 VM’s needing some GPU horsepower.
You need to patch in a PCIe 12v power cable in somewhere. A server PSU has plenty of power.
An interesting idea, a HD5970 is 2 GPUs in one.
This is doable, but I’ve never done it. If you know of any good tutorials please share 
My god I’m impressed with my own idea 
I have an HD 5970 doing nothing and I’ve just figured out how to do pass through. This would allow me to run two VMs with GPUs. The HD 5970 actually shows up as two devices in Windows and Linux.
Oh hella, please let me know the results of your experiment.
Look on YouTube for " 24 Thread PowerEdge R710 with 2xGPU PCIe x16 Gaming"
He shows how to get 12v power for the GPU in a server.

What is the hypervisor you are using?
I have an nVidia P2000 installed in a SuperMicro server with Server 2019 Hyper-V. I have that card passed to a guest Server 2019 running Remote Desktop Services. Works like a charm.
Technically any AMD card using GCN should work.
For actual SR-IOV, Nvidia does not have any options, so it is AMD only. AMD calls GPUs with SR-IOV MX-GPU.
Here are your options:
FirePro S7100x ~$180 USD used, Only available in MXM format.
FirePro S7150 - less common, I have commonly only seen x2 version
FirePro S7150x2 ~$500 USD used, dual slot
Radeon Pro V340 ~$10,000 USD new, hard to find outside of OEM systems, dual slot
Not to say that a dual GPU card can’t work, but that is not SR-IOV technically.

Thanks Cake!
But maybe it would be cheaper to just get external GPU dock and then pass that though to the VM?
I do have a spare r9 390 laying around.
I thought the external GPU docks available are all thunderbolt? Does your server have thunderbolt?
I would need to get a thunderbolt expansion card but I could grab one of these
And stick on a shelf in my rack and pass that to the VM.
Fuck nvm thats intel only xD
Hmm, I thought thunderbolt required UEFI support. For example the gigabyte thunderbolt card requires a motherboard with a specific header AFAIK.
