how is the speed between these 2 mbp? i have always use the 17" Powerbook/Macbook. Until now, I want a 15" for more portable because I have the Apple 24" LED LCD at home to work for. I would really like to know how the speed of the Core2 Duo 2.8 with 512mb 9600m GT vs i5 2.4 256mb 330m GT. I hope the new i5 with 256mb 330m GT will have better performance. I dont want to get the new book but its a downgrade from my current book. I can sell my current book for $2000 and pick up the 15" i5 2.4 $1800+tax. I mostly use Adobe/Aperture. Thanks alot!!
