Thanks, ghostship2 and hborre. I have it running now. Refresh rates makes sense. MY LATEST WOW: I didn't know you could have TWO graphics cards in one PC. I guess that's what your "RTX2060Super+GTX980" means. I checked my motherboard specs. It looks like it can handle two graphics cards but my power supply is only 700W. (Something I'm reading on the web says it might need 850W or more.) Anyway, trying to maneuver two graphics cards is above my (retired) pay grade, but it's good to know.
