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!!!!! HTH
