i5 or i7 for Macbook air

Would configuring a new 11" Macbook Air to a 2.0GHz Intel Dual-Core Core i7 (Turbo Boost up to 3.2GHz) be worth having over a 1.7GHz Intel Dual-Core Core i5 (Turbo Boost up to 2.6GHz)?

I will plan to have Firefox internet browser, Mac-version of Microsoft Office, Adobe photohshop/lightroom/elements (I'll only run one photo program at a time) as well as a Windows Bootcamp.

Any opinions?
