You need to post more info on the MBP, there are 2 different 2011 models, early and late 2011, with different specs. However, that is right, you cannot increase the processing power. However, as one poster said adding an SSD will give a definite impression of a speed increase, the difference between even the fastest HD and an SSD is a night-and-day difference in the user's perception. The whole computer feels so much more responsive. Make sure you install any SSD in the main HD drive bay, even if you add an optibay dock for a HD.We've just had a new screen and logic board on our 15" mbp and realise that it has 8gb of ram but would like to get more processing power. We are told it is an impossibility, but is it? Can anyone tell me if there is a way?
