Hello, this is my first post here but I have been reading these forums for awhile and while I do find them extremely helpful there are still some questions I need answered. I'm looking at getting the 15" Macbook pro sometime this summer and I have made up my mind about most of my options. I will be adding a normal hi res screen and adding the 128GB SSD. However I am still undecided on getting the 2.0GHZ or 2.2GHZ model, I realise this has has been discussed many times but I have some additional questions to ask. To give an idea of my usage I should be starting a computer science course in September and so I want the laptop to last me for these 4 years. This was one of my reasons for choosing OSX I want to learn Obj-C. So I will be writing a lot of code on it and other college stuff like writing up documentation and essays. I will also be using it for viewing videos and I would like to take advantage of having a mac by doing some light video picture editing. My main questions between the two models are: Will the lower clock of the 2.0 GHZ as well as the weaker GPU give a boost to battery life? Even a small amount. I have no intention of playing games at all on my Mac I have a PC for that but are there any applications apart from Photoshop that would really benefit from the stronger 6750? Does the 6490 have the power to push an additional 1200p monitor? The difference between these models for me would be about 300 euro. I can afford both models but if I don't need the extra horse power of the 2.2GHZ model I will definitely just save the 300 euro and put it towards college books and transport. Thank you for any answers you give.
