If windows fails to scale properly you're gonna have a bad time.
That is why I've upgraded(side graded as I only use desktop enviroment) to windows 8 and 8.1
This is definitely a tangent, but do you have any driver problems with Windows 8.1? I installed the preview and my USB devices would only be recognized intermittently and the nvidia drivers specific for 8.1 didn't work...so I went back to 8.
