So Christmas Just passed and my grandparents are going to help me buy a new mac laptop. I need something that wont give me any problems recording mixing or producing my tracks. I mainly use Logic 8 and Pro Tools 8 or any software synths ill come across. Initially my first thought was to go to the high end 15" MBP but as a read more reviews and forums, I noticed that the important things for recording audio is a fast hard drive and Ram. So one of my questions is would it be smarter (or cheaper) to go for a low end MBP and buy 4gb of ram and a 7200rpm hard drive? Will the upgrade in Ram and Rpm out way the 2.4ghz to 2.53ghz? Does the 6mb Cache in the high end MBP matter much over the 3mb in the low end. Also I've been hearing that the high end Macbook matches very close in performance. Would it be wise to get that and buy 4gb of ram and a 7200rpm hard drive? Or should i just ditch the whole new macbook line and buy a last gen MBP and fully deck it out lol? All in all I need something that will get me through intense projects with no problems. 13" or 15" is the size range I want to stay in. For all the Mac producers or just Mac experts WHAT SHOULD I DO?! Thanks P.S. I can't customize a mac online because my grandfather will be buying it at the Navy Exchange *No Tax*!!
