As for the 3.0ghz Celeron D? Of course it's going to be faster than the 2.4ghz P4, why? because the Celeron D will be on a 533mhz fsb just like the 2.4ghz and the 2.4ghz does not have 4x the L2 cache that the D is. The P4 2.4ghz only comes with a 512KB and the Celron D 3.06ghz comes with 256KB. So the extra 606mhz would make the difference in performance not the cache.
Also remember that a 560 is not faster than a 660 despite double the ammount of L2 cache. The 6 series are better in terms of heat and 64-bit, other than that, it's the same.
