And this the issue. You pretty much have to buy a GPU for your specific needs with what's currently available.

Talking shit about people who bought a graphics card support 3 years ago almost to the day is pretty senseless. A 3080 vs the 5700 XT one has support then and the other is just barely getting workarounds for certain use cases.

OTOH 3 years ago if that same NVIDIA buyer were a Linux user they benefitted then and it's likely it's better off today. AMD has gotten lots of driver updates for Linux and NVIDIA has probably pushed 3 changes, lol.

If you want to do AI, easily, you're just going to want to get NVIDIA. It sucks, but that's just the case unless you want to jump through hoops for what can be a simple installation. I helped my friends get Stable Diffusion running on his 7900xtx but compared to my installation it was a huge PITA and still ran slower I/t than my 3080.

Granted, using Windows and neither of us are Linux aficionados.

And if you want gaming and pretty much anything else, then AMD is a fine equivalent, as long as the player is okay with no efficient RayTracing and no DLSS. I was interested in those features so I got the 3080 a few years ago. My friend wasn't as interested and went for the 7900XT. I can understand disliking aspects of a company but I don't understand the intensity from anyone going all in on one or the other. Like, AMD is doing great things, it's a bonus that it's pretty ethical as far as we know. NVIDIA is also doing great things pushing the software side of hardware, they've just got a stint of bad leadership and have made some dumb decisions. Just like 10 years ago, NVIDIA doesn't look the same as it does today, and 10 years from now will likely be the same.

ROCM support makes me angry but NVidia also fumbled their drivers too. Their is no good option so pick your poison. I run ROCM right now with a work around on my 6900 XT to get the card detected. And i have also gone from 10 It/s to 4 or even 2 with updates. Shit sucks.
