Not sure that I get what you mean?
NVidia have, until recently, not been very friendly to the open source community.
Rainmaker:
if you only care about rendering the desktop and playing back x264 flawlessly, then any cheap 2nd hand AMD card will suffice (even down to RX280 or earlier). If you want x265 or VP9, you're going to need anything after Vega and you'll pay a lot more. For games? Dunno, I don't play them.
Regards Wayland , Still AMD best bet for now. Having said that not tried a 30xx series.
