vGpu and graphics cards less than $400

Hi,
I’m new to XCP-ng and I’m trying to configure a new system and got to the graphics card. It looks like, unless you spend thousands of dollars for a graphics card like AMD FirePro S7150, you can’t share a graphics card between VMs?

I saw the following from Olivier Lambert "vGPU is vastly different than PCI passthrough. In short, vGPU is passing “slices” of physical GPU to a VM (like vCPU for a physical CPU). This allows to share GPU load between multiple VMs with one physical GPU.

PCI Passthrough is exclusive, it “reserves” the whole PCI device for one VM."
(https://xcp-ng.org/forum/topic/295/xcp-ng-gpu-passthrough-no-gpu-found/8)

So, is the alternative to have multiple graphics cards and assign each to a particular VM?
or
Do lower priced graphics cards like an AMD RX580 work, but they have performance or other problems when shared across multiple VMs?
or
???

Thanks!

I have not done any testing, but here is the list from Citrix (which should also work in XCP-NG) of cards that support vGPU http://hcl.xenserver.org/gpus/

Thanks Tom. I looked all over and didn’t find anything like this. I appreciate the link!
