I can't imagine you'd have any issue. My jellyfin box has an fx6300 with an even older quadro gpu (600 I think), and it doesn't seem to have any issue running multiple streams at once. I'm honestly not even sure if it's using hardware encoding on the gpu, or just cpu, but in Ubuntu 18.06 it worked out of the box with the open source drivers so I haven't messed with it.
