I realize there are many threads on the issue of processor speeds in new macbook pros, and i am fully aware of running a search like, http://www.google.com/search?client=safari&rls=en-us&q=3.06+vs+2.4+mac&ie=UTF-8&oe=UTF-8. However I'm not interested in knowing if 3.06 processor speed is worth it to me, i know that, "if you have the money, go for it" seems to be a popular answer. I'm current running a 2.4 Ghz Core 2 Duo macbook pro that i bought in mid 2007. I'm upgrading to a new macbook pro and i am deciding between 2.8 and 3.06 processor. My question is if i plan on upgrading in another 2 or 3 years or so should i waste my time and money with 3.06? Or just stick with 2.8 and see what happens when in a couple years. I know that i "probably wont notice the difference" between the two, but keep in mind i'm coming from 2.4 and just curious how long 2.8 (or 3.06) will last me. Thanks for your time.
