So I've been debating for a while now about which Macbook I want to get, and for the moment I think I would like the portability of the 13 inch. I've yet to decide however if I want the low or high end 13 inch. The most intensive things I plan to do on it would be rendering and livestreaming HD content, and playing some games like TF2 and Starcraft 2. The low end 13 inch would cost me $1,149 and the specs in which it differs are it has a 2.3Ghz Intel Core i5 processor and a 320 GB hard drive. The high end would have a 2.7Ghz Intel Core i7 processor and a 500GB hard drive. So do you think I would notice a difference between the two for what I plan to use it for? Do you think that it is worth the extra 300 dollars?
