I have a piss poor white MacBook from Mid 2009 (2.13Ghz C2D) with 4GB RAM and a 160GB HD. My shell is cracking. It's time for an upgrade. Basically, I have narrowed it down to 2 options: 13.3" 2.7Ghz i7 Dual Core 4 GB RAM 500 GB Hard Drive 1280x800 LED $1,399 (Education Discount) OR 15.4" 2.53Ghz i5 Dual Core 4 GB RAM 500GB Hard Drive 1440x900 LED $1,439 (Education Discount) I'm using this computer for moderate-intense Photoshop CS5 and Dreamweaver in addition to basic student tasks. I want a future-proof computer that will last me at least 4 years. I am aware that the 13.3" has the slightly inferior graphics card, but I doubt it will hinder my PS CS5 much, if at all. In the future, I will be upgrading the HD to a SSD, so don't compare those aspects or the RAM. So basically, which one will be getting higher speeds after Turbo Boost/Hyper Threading?
