Please recommend zero-hassle video card for GUIX

[Yasuaki Kudo]

Hi,

As per the subject-line, what is the very best video chip/card for GUIX?  My 
criteria:

• I use AMD Ryzen 5 CPU (The chip has no integrated video feature enabled)
• I currently use NVIDIA with proprietary driver support provided by 
corresponding NixOS packages but now I am considering switching from NixOS to 
Guix – so I prefer to have a video card that runs natively without proprietary 
driver enabling gimmick.
• The video card should behave normally – there should be no performance 
degradation in 2D/3D/video, etc.

Cheers,
Yasu
