On Linux, you get best performance per dollar spent with NVIDIA and their proprietary driver. However if you are really keen on using open source drivers AMD is the way to go, but often going to the previous generation or two of cards will yield the best results.
So it probably depends a lot on what you want, and of course how much money you're willing to spend. Since it doesn't seem like you're playing games much yourself you should go for something reasonably priced, or you may have wasted your money a bit. Though going for the very cheapest option might not be the best either.
TL;DR it's your choice obviously, but personally I prefer NVIDIA cards since I don't mind using proprietary drivers, and theirs generally work well.
