I'm about to buy a MB Pro right now and I'm trying to figure which one would be the best for me. I'm going to be doing a lot of video editing on it and I'm trying to figure out what I need and don't need. For starters, I'm going with one of the two 15-inch ones. What is GT with 256mb/512mb? Is better to go with the 512 if I'm going to be doing a lot of video editing on it? And as far as processor, do I go with the 2.93Ghz instead of the 2.66? Those are really the only questions I have. I know I have to go with a 7,200 rpm hard drive. If you guys have any other helpful tips, that would be great. Thanks guys.
