I paid $845 after tax for a used 7900XTX back in June 2023 to max out my 5800X3D system. I figured by the time I could afford a 5090-class GPU that would make a bottleneck out of my 5800X3D I might be able to skip DDR5 completely. Now I'm unsure if 5090-class performance will ever be available for less than $1k.
