I wanted upgrade my Sony e. presently I have i5-450M but I want to upgrade it from i5-450M to the Sony i5-520M CPU’s. I have searched about this and have found that the difference I spot in the specification is .33GHz more turbo boost. Is it worth getting the 520m as it seems to be almost identical to the 450m? Is there much of a variation in performance between the 450 and 520? Please give information on this.
