Ok, so I am pretty new to macs and have decided to buy a 15" MBP after the conference updates. I am very pleased with the updates and the price cuts they have made but I can't decide whether I should get the 2.53ghz or the 2.66ghz. The reason I am debating this is because of the video card. I doubt the speed with the processors will be much different but I have seen a few posts mentioning that once snow leopard comes out, having the dedicated gpu will help. I was wondering if this was true. If so, how much of a difference will it make. On another note, I will be studying music business in college and plan on using my macbook for recording purposes so I don't think the video card will make too much of a difference. I also don't play any computer games whatsoever. Thanks for all replies.
