P35 would do you fine, it's just that you're forking out £111 for one and in that price range there's plenty of P45 ones. There is a review of an Asus P45 somewhere and it's very positive, but like I said P35 would do you just fine (MSI P35 Neo2-FR, Abit IP35, the Asus you mentioned etc) and would cost you around £70ish.
