Thanks for all replies. I will definitely look into the links.

A 3060 wouldn't be enough of an upgrade compared to my 2070 Super, in my opinion. Maybe 3090, not sure yet... Anything under 16 GB doesn't really seem wothwhile.
If I should get a new system soon, I guess I could always consider replacing the graphics card again in a few years, if high-VRAM cards ever become standard and affordable.

Is SLI still a thing? Could I tandem my old 2070 Super with a new 16GB card for a total of 24GB? And/or could I get a second 16GB card later (maybe the exact same) for that purpose?
As you can see, I'm not that up to date anymore... I wish I could just buy an external 32GB chunk of VRAM and plug it into a USB port. xD
