Have a 3090. But I will probably get a 7900 card instead. I've discovered ray tracing isn't implemented well in the majority of games that try, and I want to switch to Linux. Nvidia's drivers suck for that and I've had issues trying with my 3090. So it looks like AMD is the better option for me.

For what it's worth - I just made the switch from Nvidia to AMD. I was Nvidia ride or die for the last 15 years. (Multimedia work). 

Just switched over to a full AMD build with a 7900, and holy shit it's nice. Across the board everything is just simpler and easier. 

Less random crashes and wierd bugs. Less bullshit driver updates from Nvidia every time a new fucking game comes out. Renders done are fast, stable, and reliable (accurate estimates instead of hanging at 99% because Cuda cores are just so special).

Overall performance is amazing, and even the bloatware they include is actually useful and easy to operate. I've got all my old games running on ultra, and it took like two clicks with AMD software. Nvidia was requiring me to set up an account and log in just to change fucking game settings.

Anyway, in the 4 weeks I've been using AMD, it's clear that Nvidia can eat shit and die in a dumpster. Not only is AMD cheaper, it's honestly just a better experience all around. I'm never looking back.

(TL:DR - Nvidia is pretty much all marketing fluff to get consumers to buy hardware that will give them an overall worse experience. I'll gladly take a marginal 10% performance hit to my system if it means I never have to use Nvidia driver software again.)
