I was comparing Windows 8.1 , Windows 8 and Windows 7... I really don't know how to compare or is there any comparison but I just wanted to ask Which one of the three is better for gaming that would give me more performance.. I don't mind Metro in case of Win 8.. Touch is not a matter of concern and I don't have a touch screen monitor to have the Touch enabled.. So in terms of gaming performance which one you guys would prefer..? I would appreciate if someone has graphical scores of gaming performances on these systems..
