I also use my GPU for hobbies and work. My hobbies are game dev (nothing hardcore GPU-wise, just some mid-poly modeling), gaming (mostly indie, though occasionally SP AAA), and random SW-dev projects (e.g. I’m building a Lemmy/Reddit clone). For work, I’m a full-stack web dev and don’t do CUDA work (and I have a separate work-provided laptop), just occasionally run renders of things (mostly web-based three.js stuff). So for me personally, I’d only really see a benefit for running some of the latest games, which is incredibly rare since I honestly don’t have a ton of time to keep up with things (e.g. I’m finally starting RDR2 after owning it for years). I game in 1440p, and most games don’t tax my GPU (RX 6650XT). If I need CUDA, I’ll just rent space on AWS or something instead of running it locally.
So I care a lot more about Wayland support (I have monitors with different refresh rates) and driver stability (I run a rolling release, and Nvidia causes issues at least a few times/year) than top tier performance or latest features. I’ve been on Linux longer than Steam has, and I’ve honestly only been playing more games because Valve has made it so easy. For me, Linux comes first, gaming second, and AMD provides a high quality product for my use case. I used to use Nvidia because ATI used to be worse on Linux, if you can believe that, but I upgraded after COVID because Wayland got quite stable.
