We actually moved beyond that a few posts ago, but that's okay.
Out of curiosity - why do you think the base model will come in at 2.5 instead of 2.4?
why not .. the penryn T9300 (likely update : it costs the same as previous processor at its release date) runs on 2.5 ghz and not 2.4 .. u really expect the base model will be T8300 with 3MB L2 while the med range has a 6MB L2,,. nah ........ dats y
