I am unsure whether to get the i5 or i7. I have currently ordered the i5 with upgraded 8GB of RAM and 750GB hard drive. I will be using my MBP for Pages, Keynote, Numbers, Internet, some small pieces of editing and possibly some games. For an extra £80 - roughly $110 USD !? . . I could upgrade to the i7 with 8GB of RAM and 750GB hard drive. Will it make a big difference in the gaming and multitasking or will I be fine with the i5. I understand the 13" is bottlenecked with the lack of dedicated graphics card for gaming. Will the i7 prolong the life of my MBP?
