I was ready to order my son a new MBP from the refurb site then I started reading all the threads on freeze ups on new MBP. .For the same price on Apples refurb site I can get either the 15 inch i5 2.4, 4g, 320g $1599 (canadian) or for the same price the 15 inch 2.66 Core 2 duo, 4g, 320g, with Nvidia geforce 9600M GT. Which would be the better computer? He does a lot of work with imovie. he is not a computer repairman so I want something reliable as he will be travelling with it and can't be running into the Apple store. Thanks for any help.
