I want to get the new MacBook Pro for playing games and video editing and I'm on a budget. Is the 15 inch worth it? I hear the 13 inch is a i5 duo core and the 15 inch is the i7 Quad core But is it worth it on a budget and how much faster will the 15 inch be. If it is 2 or 3 times faster yes I will cough up the money but if not 2 or 3 times faster than I will not. I also hear that the 13 inch gets very hot and the 15 inch is much cooler.
