Depends completely what you do with it.Hello, the rMBP can be upgraded to 2.7GHz quad-core Intel Core i7 (Turbo Boost up to 3.7GHz) with 8MB shared L3 cache. Let's put the cost aside, what advantages does the extra .1GHz and 2 MB of shared L3 cache offer?
Slightly faster processing speeds, meaning power hungry programs such as handbrake and final cut will finish slightly faster.

Well, the posters before me have already answered the question, I just want to make it a bit more clear.
Imagine you are a photo professional and you make your living by processing digital images in Photoshop. A 2.7 CPU will allow you to process a few images more per work day (given that your workflow is flawless), because filter application etc. will be faster. Thus, you will be able to complete your orders quicker and potentially earn more money. Of course, if you only get few orders in the first place, the faster CPU won't save you anything (except maybe a minute or two of free time).
Many people think that buying a faster CPU makes it more "future-proof". Essentially, this is wrong. If an i5 chokes at some future application (that is, it is unable to process the code in a reasonable time frame), so will the fastest i7 - in the end, the performance difference between the two is less then 15%, and thats under maximal throughput. For tasks which do not tax the CPU, there will be no speed difference at all.
This is why I wrote "given that your workflow is flawless", meaning that the person spends more time processing the image rather than setting it upHonestly, no, it won't allow you to process a few images more per work day - because the rate limiting step isn't the processing, it's the thought process itself. It's really only in tasks where the CPU is running at 100% for a significant length of time where there'll be a noticeable difference, and even that will be slight.
