Info needed on 13″ mac book pro

Hi. I am curious whether the new 2011 13" mac book pro is fast and can handle 5DII?
I have the old one (2010) and it is slow when I try to edit 5DII files.
My choice would run only at the 13" ones since I am always on the go and would like it to be portable.
Can anyone help me with this one?
