I am gonna buy a MBP 15" next week, but the question is which one to get. The 2.53 Ghz or the 2.66 Ghz? This will be my first Mac ever... the reason I am going with Apple is because I am into music production and I want to hook music equipment up to the Pro. I've been asking around and most people say that the 2.53 is cool enough. There's a $300 difference between the two so I am wondering if I should just spend that money on software (i.e. parallels, office mac, etc.) and apple care. Thanks in advance for all ur advice.
