I am jumping into the film making buiseness and need advice on buying the right Mac for my needs. Everytime I tell people I will be downloading videos for editing, I am told the Macbook Pro is the way to go. However, the only difference I have seen between the Pro and Macbook is that the pro has NVIDIA GeForce 8600M GT with 256 MB and the size of the screen. What exactly is NVIDIA and does it apply to my needs? Are there any other factors I am overlooking? So basically, can I save a little and go for the 2.4GHz macbook or should I buy the macbook Pro?
