Hello! I'm gonna buy my first 13' Macbook pro and I was wondering if there's a big differences between the mid 2009 2.26GHz Intel Core 2 Duo and 2011 i5 Macbook Pro. I found the mid 2009 for $750 and the 2011 for $900. I don't think I will be doing much video editing, just internet, chat, games on Steam, and for school.
