currently I have a nvidia 1650 super set up with a passthrough on proxmox then attached to the jellyfin docker container. I have too considered getting an arc as it seems a good deal for thee functionality.
but as someone else has mentioned it can apparently take a decent amount of effort to make it work. if your willing to jump through the hoops then sure its probably a leaning exercise but I decided to just use a cheap older card for now until support is a bit more "out the box" then maybe try again (or the server might get just a hand me down from a desktop upgrade too)
also I don't really need the upgrade with a 1650 super and a E5-2618Lv4 my use case is more than covered.
