So i bought a high end 15 inch Macbook pro at the beginning of September. I also added the extra 8Gb of ram. I chose this because i am doing an engineering course at university so i thought that during my course i will need to do a bit of CAD. I also wanted to "future proof" it so i went for a high spec. My question is what is the difference between the one i bought and the new macbook pro 15 inch, i know it has an extra .2 Ghz, a different graphic card 6770M instead of 6750M. How much of a difference does this make? Also how much of a difference would the 7200 rpm make instead of the 5400 rpm. I ask this because a friend of mine is interested in buying it off me and i don't mind making a bit of a loss to upgrade, but wanted to know if it was worth it?
Thank you
