Got a new PC handed down to me. And now have my old one collecting dust. It has a dedicated GPU (GTX 1060 6GB VRAM) i guess the most obvious thing would be an AI model or maybe jellyfin (which is currently running on a raspi 5 just fine for), but was wondering if you maybe had other suggestions?
Regarding Jellyfin, if the PC you got has an Intel CPU then using Intel QuickSync would actually easily outperform the NVIDIA card for transcoding.
Up until very recently I was using a cheap i3 to power my Jellyfin instance that often has 5+ streams going at a time. (The only reason I upgraded was that I had a friend getting rid of an i7 from the same gen lol)
