Macbook Air - i5 vs i7 I am buying a Macbook Air and would like to know about the difference between the i5 and the i7 option. The i7 is only 100mhz faster and has 1mb of extra cache on the CPU. Does that small difference make a big difference to performance? Or is it so small that its not really worth the AU$100 extra?
AnandTech did a report comparing the two options and came to the conclusion that there isn't really a noticeable difference.  Just 7-12% improvement on certain benchmark tests.  

Below are the figures they got for reference.
