I currently own a 2GHz Aluminum MacBook. It's been OK, but it doesn't run Final Cut Express that well, and it's a bit slow on graphics-heavy software. I've recently acquired a MacBook free from a rewards site, but I'm torn on whether or not to keep it. The model is MC516LL/A, and it has a 2.4GHz processor with 320M graphics. I'm thinking about selling it and buying a used MacBook Pro for around the same price. I was looking at the MB470LL/A model, which has a 2.4GHz processor and 9400M/9600M GT graphics. Which is the better option?
