It depends, if you want to run llm data center gpus are better, if you want to run general purpose tasks then newer silicon is better, in my case i prefer build to offload tasks, since I'm daily driving linux, my dream build is main gpu is amd rx 7600xt 16gb, Nvidia p40 for llms and ryzen 8700g 780m igpu for transcoding and light tasks, that way you'll have your usual gaming home pc that also serves as a server in the background while being used
