Which Macbook pro retina model to buy?


I am confused between 2.4/8/256 model and 2.6/8/256 model. ive read a bunch of reviews but cant seem to decide if the processor upgrade is worth it. i plan to use the laptop for browsing and document editing and occasional handbrake encoding of videos as well.

I have seen the benchmarks for both the processors but they dont make much sense to me. So my question is does the processor upgrade show any significant improvement in day to day usage.

Would really appreciate some advice and pls share your experience.
