AC20 Video card does not support OpenGL 2.0?

NVIDIA GEFORCE GTX 470
NVIDIA GEFORCE GT 640
NVIDIA GEFORCE GT 720

These cards worked fine with Archicad 19 but when I try running Archicad 20 I get the following message, attached.

All cards have updated drivers and according to the specs on the website all of them are capable of running OpenGL 2.0.

Do I have to get new cards for all three of these computers?

It seems to me that they should be able to support OpenGL 2.1, not OpenGL 2.0.
What is your operating system?

Windows 7 Professional for all of them.

Tried updating the drivers for one of them just now, then Open GL wasn't working for AC19 or AC20. Did a windows restore point now I'm back to square one.
