Much difference between Macpro?? Adice plse

[k11jrp]

I am looking at buying an Apple Macbook Pro. I have 2 choices, the 2.2Ghz i7 15" display (released in February 2011) or a 2.3Ghz i7 15" display (released in June 2012).

Neither of these are the new Retina display but the latter 2.3 has a turbo boost to 3.3Ghz i believe??

There is about a £200 difference, it wont be used for anything to taxing so is it really worth it? All other specs are the same between them so basically you pay £200 extra for a faster chip and a newer release date...

Comments please, thanks in advance

The June 2012 one you could take out applecare and extend the warranty for 3 years.
