what are turbo boost and cache useful for?

[MacCrackAddict]

what it says on the tin, i dont really understand what the i7 MBP 13" turbo boost and cache over the i5 version means. what will it speed up? i do a hell of a lot of video conversion, FCE, Aperture and am a heavy user of rapidweaver. How better off would i be with these things and what do they do?

sorry to sound like a complete noob!!!

Turbo boost will basically shut off a processor core and augment power to the other one to achieve a better clock speed(read, faster processing) for single-threaded tasks.

More cache is better, although what it does is not something I know.

Turbo Boosting is the CPU increasing the cycles temporary for an intensive task. It eventually slows down once it reaches a certain temperature.

Cache is the CPU's temporary memory. Basic desktop level activities are stored in the cache.
