xps m1330 processor question

[spaceman]

I've been waiting for a 2.5ghz (6mb cache) with the system spec i'm looking for to turn up on the outlet site with no luck yet so will probably go for a 2.2 or 2.4.

probably a stupid question but will the 2.2 with 4mb cache or the 2.4 with 3mb cache be the faster machine?

thanks, i've also had a search of the web and it also looks like the 2.4 is the one to go for as you say the battery life is longer - performance is ment to be slightly better than the 2.2.
