I'm going to be getting my first mac tomorrow. Probably the i5 or i7 13'inch Macbook Pro. Still unsure of which one to pick. I know that the i7 has a overall performance boost compared to the i5 but is it worth the extra 300 dollars? I know the i7 comes with 8gb of ram compared to the i5's 4 gb of ram which saves me roughly 60 dollars.
