I know many have asked the question about which Macbook Pro to buy but I have not read a sufficient answer for my situation. So, thanks ahead of time for the advice. I want to buy a new MBP immediately. I need it for both raw and jpeg photo files (Nikon d300), protools music recording/edits, and about three to four movies edits per year. Can I get by with the 2.4 or do I need the 2.5? I'm not sure how much the extra 6MB L2 cache and 512 graphics card will improve the performance of the programs I run. Also, do I need a 7200 rpm drive? Thanks for the help.
