    When it comes to Mac's, I love the superior performance, the clean lines and stylish good looks. Last year I upgraded my G5 Quad with a 27" i7 iMac and all I know is that the difference in performance is stunning!

    My question relates to my MBP, currently I have a 15" 2.53 C2D with shocking battery performance (its the late 2008 model - looks the same as the current model but it has the removable battery cover).

    Assuming the cosmetic appearance (yes, I'm a "must have the latest design" snob!) and other features of the next MBP change, I'm thinking of ordering (hopefully later this week, fingers crossed) a 17" 2.7 i7-2620M (assuming that's the top spec).

    In laymans terms, can somebody please explain what performance enhancements I might expect from what seems like a very small increase in processor size??

    Many thanks in advance .... :apple: lover

    Would be very noticeable in my opinion. Basically, GHz in no way really matters anymore, it's all down to architecture now-a-days.

    This is all based on guesswork and is utterly stupid to expect all this, as you may just disappoint yourself. However, don't let processor clock speed fool you; it may only be .17ghz higher but the performance of the i7 processor far outweighs that of the core 2 duo. Even at a slightly lower clock speed I would recommend the i7 over C2D anyday.
