Per the subject... Current gaming desktop has Win 7 loaded on a 1TB SSD. Another 1TB SSD will be installed with Win 10 at the same time I upgrade the video card from GTX 970 to GTX 1080 Ti. Win 10 will be the primary Boot OS with choice to Win 7 via Easy BCD. As far as upgrading the video card, I assume I simply just load the newest video driver into Win 10 OS just like any other system build and use the existing driver on Win 7. What's going to happen on the Win 7 OS? Will the updated video card be transparent to Win 7 OS, or will it know there's been a HW update and will that screw everything up?
