I think it depends. when you run many things for yourself and most services are idle most of the time, you need more RAM and cpu performance is not that important. a slower CPU might make the services work slower, but RAM is a boundary to what you can run. 8 GB is indeed a comfortable amount when you don’t need to run even a desktop environment and a browser on it besides the services, but with things like Jellyfin and maybe even Immich, that hoard memory for cache, it’s not that comfortable anymore.
