your graphics card might not be the problem - this error seems to happened to others & you should always check other things before replacing a card without checking if it is the actual card.
that being said it hasn’t been long since I had to replace mine but it was actually the card !
did a google search which you should check out some of the solutions & dig deeper:https://www.google.com/search?source…=1566230981368
hope things work out for you! - still NVidia but the 1080 series will do VR - probably not that well but if you plan to upgrade get a VR Capable GPU
