I intend to buy a new MacBook Pro (15), but I'm not really sure what options I should choose..
Is choosing all the bold-options overkill? What do I need for Avid editing? (read the avid system requirements, but what do you guys think)?
Is some of them unnecessary to have? What of the options below should I go for?
IMO what you need for Avid Editing is lots of screen space (you can survive with a 17" screen - if you go for the 15" screen you'll find yourself realising you need a second screen very quickly) and lots of FAST external hard drive space (don't use the internal drive for media).
There will always be occasions when the higher spec processors and extra memory will make things a bit better, but most of the time when you're cutting the 2.2Ghz i7 and 4GB memory are ok.
