An AMD GPU has been less work for me running Linux (Kubuntu at the moment). The nvidia card worked fine, but I had to manually update drivers about every week. Had games I was trying to run complain whenever drivers were not the most current version. I now have an AMD card, popped it in, everything works with no hassles. I've built my own systems for decades, but now would probably recommend buying a pre-built. It's fun to do, but there aren't really any cost savings doing it now.
