3d heavy modeling
Depending on the program of choice to go with AMD over NVIDIA will heavily impact your performance as cuda is better optimized than rocm. For me rocking rtx3060 it was hit or miss. It mostly depends on the distro if they choose to package the NVIDIA drivers out of the box. Some distros value freedom over usability. Right now I am daily driving bazzite and I am happy with it. For drivers its self I didn’t notice any major issues.
From your convoluted explanation I assume you have one PC already and you want to upgrade. I would just get a new one for work stuff and old one set up as “light work” as you put it or hook up to the TVs
I have already switched after arch out of nowhere disabled ipv4. I tried using fedora atomic but the lack of non-free software just didn’t work for me (blender + hybrid NVIDIA graphics). I am using bazzite for a week or two and so far so good.
