I use my macbook pro for heavy music related tasks. such as mixing in logic (last project i was working on had 70+ tracks). and often have more then one music processing program open at the same time. i was wondering if the cache (2mb) difference in 2.2>2.3 update will play a noticeable role for me? all the other options to normally save for, im going for either way. i can afford it, but of course i dont liek throwing money in the wind. im just not sure if there is any reason for this update... wat do you guys think?
