What Computer to get?

Hey,

I'm posting this here as I'm having more of a push towards a Macbook Pro, Now the new 2012 Macbook Pros (not the retina) are way to expensive, and the October 2011 - which I understand are the 2nd newest ones, are more in my price range.

I found a 15.4" for £1,000 or shall I get a Mac Mini (2.5Ghz, i5, 120SSD with 8GB RAM) for £675?

I honestly like the portability, but it's not needed. Which one is more powerful, better for gaming (Diablo 3, Minecraft - low level performance games)?

 

Sorry, I actually changed Macbook Pro, it's the newest 13inch (15.4 was an old model!) It's dual-core 2.5ghz, so they are very similar, has Intel HD 4000 as well.

Thanks

Or, would it be more sensible to get a quad-core i5 2.2GHz Macbook Pro - either October or February 2011?
