I have a base 2010 13" MBP with the core 2 dou chip. I already know I want to upgrade this year but to what? The most cpu extensive thing I use my MBP is to encode my bluray movies to mp4 to be played on my Apple TV's. Apple charges $500 for going with a 256gb SSD and I can get a 256gb Crucial M4 for $214 or 512gb Crucial M4 for $400 on Amazon which to me, would be a must. I'm fine with a 13" display but just how much better is the quad core i7 over the dual core i5? I'm sure either has to be way better then what I have now but $400 faster? I'd love the flagship 15" MBP but can't afford that. What does everyone here think I should go for as far as the MBP and SSD?
