So i was talking to a certain individual who has an age and also experience in the field and he said that a 1.1 GHz PC ran better on windows 7 than it did on XP. He also mentioned that windows 8 is smaller, and more efficient for that matter(yes i know it is intended for tablets and so, so i am not interested in any opinions on the completely different UI and the effect on the users comfort). Does anyone know more about this matter?
