Hello,
I was trying to use Stable Diffusion but i get an error about gpu too old, so this may be the final motivation to buy a new
graphic card. Can someone point me out to a tested working exact model to buy?
Thank You

The requirements for Stable Diffusion vary all over the map (except AMD graphics is not supported on all "forks")
https://www.digitaltrends.com/computing/stable-diffusion-pc-system-requirements/
The original minimum was 10gb of video memory and an NVidia card. That typically is GTX-1080Ti which has dropped in price (used) due to newer cards out but can run hot if not liquid cooled.
The z820 is PCIe Gen3 and an RTX 2080ti is also 11gb memory.
The 30xx and 40xx NVidia are Gen 4 but should be backwards compatible to Z820
RTX-3060 has 12gb and probably is best value
