Light gaming seems common, asahi linux streams have have minecraft, tux racer, mario kart, and related. Seems like a fair amount of ML (both inference and training) going on. PyTouch now works with CPU and GPU (via metal), and seen some posts on using the special matrix accelerator (AMX) to achieve a 7x improvement over the GPUs. One bonus is the GPU (and AMX) can access all memory, not just the 8-16GB that's common on GPUs these days.

I'm not a heavy gamer, but having some 3D is nice. I'd likely buy a 7900 (non-x) or 7800X3D if buying now, but not going to spend $800 and up for current gen GPUs, maybe get a 3060 or 3060 Ti. The Mac Studio is looking pretty promising, hopefully it's refreshed with the M2 CPUs RSN.
