My dad told me he would buy me a Macbook Pro (finally!). Problem is the new 2012 model is not yet available here in our place and getting a 2012 unit from another country would be more expensive with shipment fees and all. Question is, if I choose to get the MBP 2012 model will it be worth the extra money? I'm planning to get the 13 inch. Does the Ivy Bridge, HD4000, USB 3, and 1600mhz of RAM give the MBP a noticable performance increase? By the way, this would be my first Apple computer so I have no idea about how they perform over PC's. Thanks in advance.
