From my experience using AMD cards, the linux drivers have some serious issues, to the point where on-board intel graphics would give me much more stability. With AMD cards I would get excessive screen tearing just from dragging or resizing windows in a desktop environment. The advantage of AMD is that their open source drivers are acceptable, where nvidia's open source drivers are not great.

In terms of stability, the proprietary nvidia drivers are simply the best, and gave me significantly less issues. For my daily workstation I even ended up replacing my (expensive) AMD card for an nvidia one because the desktop environment felt like it was running less than 10 fps, and it triggered me to no end.

Even if AMD gets equal or even better performance than nvidia in gaming environments, I am not willing to compromise the desktop for that.

If you don't mind using the closed-souce nvidia driver, I strongly suggest nvidia.
