Background: I have a 2010 2.66 dual core i7, 4GB RAM, 120GB Intel SSD. I do occasional graphic design and video converting. No gaming. Going to get a new 13" model, just don't need the size or dedicated graphics of the 15". Was going to go with the i7(that way I'm not downgrading processor speed), but considering I could get the i5 for significantly cheaper at MicroCenter, I was considering it. That being said, I'd really like the higher end one, but since I'll be swapping my SSD into it, the only real upgrade I'm getting is .4GHz of processor speed and a different[better?] processor. Is it worth it for the i7 one though? Is there going to be much of a performance increase?
