but what you want is 2.8 533 - you can oc it up to 3.4-3.6 and they are dirt cheap
the 3.4's are really expensive - they were a few months ago when i last looked
the 3.2 is half the price and 3.0c runs 3.5-3.6 super cool - i have been running a 3.0c in shuttle since 9/03 24/7 and i am typin on it now - since it still works fine. next to me is C2D with dual x1950's -- i still use the 3.0c.
In that case, what are you trying to get your machine to do? List your system specs and what you want to do and maybe someone knows of how to get X to be faster. Perhaps you need more ram, or a better video card. Faster CPU isn't always the answer for everything.
