In your case, get the Pent D 805. Not sure, never checked up on it, however, I have been told it has a multiplier of 20 on it. Meaning you can Oc it like none other. Its going to be like 66 dollars too, after Conroe gets to Market. Or something. I dont know, behind on all the stuff.
Anyways, friend told me, it can be Oced up to about 3.6, to 3.7ghz on air. Mind you, you are gonna need a good h/s and awesome air flow, but it can be done.
Or so I have been told. So T/F guys?
