What's the difference between mother boards, "Asus Z97-A: Windows 8.1 ready" and Asus Z97-A: Windows 10 ready"?, i cant find 8.1 specs anywhere. I know one is designed to handle windows 8.1 and one is for windows 10... but what is actually different? i run windows 7 on the 8.1 mobo, but if i decided to get an upgrade would it be recommended that i upgrade my mobo to the windows 10 version?
