Laptop CPU Help Please!!?

I am currently building a laptop on HP.com. Is it worth the $50 to upgrade to the next tier processor when going from 2.0GHz to 2.26GHz? Considering all other things equal? (2MB cache, 1066 FSB). (If anybody needs more specifics, i am looking at going from the Intel Core Duo P7350 to P7550.) Thanks in advance.
