Unraid NAS - GPU or not?

[Aelred89]

I've recently switched from a windows desktop to a Mac Studio so I'm looking to cannibalise my old rig.

Would my Unraid NAS server benefit from a RTX 3080 for hardware decoding or is the Intel 10400 CPU enough for that task?

Is there any other benefit of chucking the GPU in the server?

Thanks!
