I'm buying a new laptop next month, I'm already dead set on a MacBook Pro, so that's out of discussion, it's going to be my first recording experience ever so I read a couple of threads here to pick the most suitable for me. I'm torn between a 13" MBP with i7 quad core 2.7 gHz and a 15" MBP with i7 6 core and 2.2 gHz. Is there any real difference for a beginner with these clock speeds? I'm guessing the number of cores has a bigger impact on running amp simulators and plug ins but I'm not entirely sure. I read the articles on multi threading but it still isn't very clear to me. Thank you for your answers!
