i have a choice: MPB core 1 duo 1gb: 1150 (im gonna upgrade to 2gb for about 100 extra) MPB core 2 duo 2gb : 1600ish both will be 2gb RAM. Im gonna use final cut express, logic pro, and upgrade to Leapord. but im strapped on money (im a college student). so my question is: is core 2 really worth the extra money on Macbooks? is 64bit really that important? (i will be using this laptop for 2-3 years btw). no, i dont do gaming and i dont do 3d graphics, but i do studio quality movie making, imaging, and music.
