Hello I will be attending grad school this fall and I would like to get a notebook mostly for word processing, email, keynote presentations. I know pretty much any laptop made in the last decade will do that, and since I don't have much money I've been planning on getting the base model Macbook. I'm an artist and photographer, and since I mostly work with film and print in a dark room, I don't really expect to use the computer much for my work. However, I'll consider the possibility that my work may change in the next few years and I end up working digitally for a project or two. I recently did some digital prints from scanned 4x5 negatives. To make 24x30" prints I was working with files around 1.5GB files in photoshop. I found the G5 Powermacs I was using to be quite slow, it would take up to 15 minutes to process an action or save a file. It's likely that any digital work I do in the future will involve larger prints and therefor larger files, probably up to 4 or 5 Gigs. What I'm wondering is, does the graphic card difference in the Macbook Pros effect how Photoshop will handle those big files? Or is it purely processor power (in which the Macbooks and Macbook Pros are very similar)? If it makes a big difference, I may go with a Pro model just to make sure I'm not limited. I'm sorry if this has been asked before, I did a search but couldn't find any threads to similar. I should say that I've seen people mention big difference in how the two Macbook types handle video and audio production, but high resolution still images I'm unclear about.
