Hi @Jcg116 

I'm sure you have your reasons for running an older version on older hardware.  It sounds like you plan on purchasing an older Intel iMac, since, if you already have one,  whatever you have is your only choice..

AC 24 will run fine on Monterey (two versions of macOS newer than Catalina), so for security update reasons, I'd at least consider upgrading your OS to that from Catalina.  It's free.

As for cards, Graphisoft has this KB article:

https://community.graphisoft.com/t5/Installation-update/Recommended-Graphics-Cards-for-Archicad-24/t...

Interestingly, that article mentions an issue with AMD cards and Catalina ... but I had a 2017 iMac Pro with an AMD card and all was fine.

I think any of those listed would be fine - although I would lean towards a card with 8 GB of VRAM if you do heavy rendering.  For normal Archicad operations, any of those listed would be fine.
