For those of us with older servers it's cheap and easy to buy a low profile dedicated GPU and drop it in there then it is to upgrade the server. You really don't need the latest and greatest to run something like Emby, at least for a household and not too many parallel streams.
OS: Ubuntu Server 24.04 LTS
CPU: Xeon E5645 @ 2.40GHz x2
Motherboard: Supermicro X8DTN+
RAM: 48GB
GPU: NVIDIA GeForce GTX 1050 Ti
Storage: A little complicated since this server is used for quite a few things. 11x12TB, 12x6TB, 1x120GB SSD, 3x3TB, and 3x24TB; spread over a 12 bay back plane and a 24 bay disk shelf. For Emby concerns, there is 215TB for bulk storage of media, and a shared 6TB of fast storage for Emby itself.
Clients: 5 in-home devices, 6 if you count music-only. 1 remote.
Library: 1970 movies, 1956/51630 shows/episodes. A large portion of which is from my own owned media, remuxed by myself.
Granted, most of my clients do not need to transcode and can directly play most things. I simply don't see the need/want to "downgrade" via transcoding media that I purchase and remux to have in the highest quality available.
