Dual core i5 vs i7 for modeling only?

Hi guys,

For purely modeling purposes, will there be a significant difference in performance between a dual core i5 @2.4GHz and a dual core i7 @ 2.8GHz? Does the processor really limit the system, or is it RAM that makes the difference?

I’m looking at 13" Macbook Pros and need to decide where to throw my money. I wouldn’t even try to render on a macbook, so it’s not worth going to the 15" for the discreet graphics.

Any input would be greatly appreciated - thanks!

i5 is sufficient for your processing needs, but if you have money to throw around go with the i7.
