So this Christmas I was thinking about changing my gtx 950 to an upgraded 1060. My questions are: will it be compatible with a ga-H81M-S2H MoBo? I've been looking around and looks like it but just to be certain. And my second question is: do I need to clean the previous drivers in case there is some kind of conflict between the new ones and those or can I just change and download the new ones? If so, could you recommend me any program that does a clean removal? Because I've been looking and looks like the default system that NVidia brings is kinda crappy. And finally, would I need to do some kind of OS reinstall or nah? Thanks for answering.
