That's problematic as Nvidia's support for open source is
at best spotty and if you're doing something a tiny bit out
of 'usual' - - - - terrible.

My previous system I started using 3 - 570 nvidia gpus and
when 2 failed some 8 years i I replaced them using only 1 -  1650 Ti.
My issue was that I wanted to using a HDMI monitor as part of
my group - - - - - the results were a system that would need a restart
every 2 weeks and it was a royal PITA with the nuisance.
My present system is quite more reliable but today's browsers
are now also increasing the issues - - - - argh!!!!!
