I have a Dell Optiplex 990 i7-2600 refurb that came with Win 10 Pro installed even though that was not the original OS. After Win 10 broke the Intel HD Video drivers I can't find a way to replace them because everything I've tried refuses to install saying it is unsupported hardware. Neither Dell or the refurb company can help. So I figure the best solution is to install a new video card. I'm not a gamer, just would like OpenGL support to at least level 3.0 for an app that needs it. Would appreciate suggestions of suitable (i.e. half-height PCI) video cards that would be compatible with this computer and have the required OpenGL performance. Since it's an older machine, inexpensive would be good. Thanks!
