I was thinking of overclocking the CPU from 2.4 ghz to either 2.53 ghz or 2.66 ghz, to make it comparable in performance to the higher end models. I know for desktops it's very silly to buy the higher end cpu, because a little overclocking will give the exact same performance. Anyone knows if the same holds true for laptop CPU. ( I think the i5 2.4 ghz and 2.53 are identical except in clock speed, so a little overclock to 2.53 ghz should atleast be possible right? ) And are there guides on how to overclock on a Mac/OS X?
