Nvidia cards are more powerful, but even if others never catch up they could still be solidly “good enough” for gaming. I have a newer Nvidia card and my computer is feels so wildly overbuilt. The only thing I wish I had more of was SSD space, but that’s a different problem.

Unless you’re a professional competitive gamer, in which case this is actual work equipment, the difference in performance between medium-tier and upper-echelon is probably not worth it for the average consumer.
