Hello MacRumors! I am starting college in a month or so.. I am going to need a new laptop, since I don't have any PC at all and I am looking to buy a Mac. This is going to be my first Mac ever. I've already have an iPhone 4S and a iPad 2, which I used a lot in High School, but it's not going to be sufficient for college, perhaps on those rare occasions where a notebook isn't required. I am mostly going to use my MBA for school stuff, like writing essays, surfing the intertet for personal use and for researching, itunes and youtube, you know the deal. I don't really use photoediting programs but I might be required to in school, but it'll only be lightweight. Also I've been researching that MBA's can handle some casual gaming like D3 and a bit of WoW, which I might also be using it for. I am going for the 13" MBA with 8GB of RAM, but here is where i am getting confused. Now I know I said casual gaming, but I don't play more than 1-2 hours every few days, but when I do play I want things to go as smoothly as possible. So here is my question - i5 or i7? Will I feel an increase in power while really using my MBA at it's maximum when pushing it with intensive programs like D3 or will it be minimal? Now the money isn't really the problem, neither is the amount of storage I get from upgrading to the i7. But if I can save the money I would of course like to, though if the investment is going to be noticeable I wouldn't mind spending the extra money. Thank you!
