I’d say in general, the advantages of Nvidia cards are fairly niche even on windows. Like, multi frame generation (fake frames) and upscaling are kind of questionable in terms of value add most of the time, and most people probably aren’t going to be doing any ML stuff on their computer.
AMD in general offers better performance for the money, and that’s doubly so with Nvidia’s lackluster Linux support. AMD has put the work in to get their hardware running well on Linux, both in terms of work from their own team and being collaborative with the open source community.
I can see why some people would choose Nvidia cards, but I think, even on windows, a lot of people who buy them probably would have been better off with AMD. And outside of some fringe edge cases, there is no good reason to choose them when building or buying a computer you intend to mainly run Linux on.
It depends on the type of productivity TBH. Like, sure some productivity use cases need CUDA, but a lot of productivity use cases are just using the cards as graphics cards. The places where you need CUDA are real, but not ubiquitous.
And “this is my personal computer I play games on, but also the computer I do work on, and that work needs CUDA specifically” is very much an edge case.
