Something is jacked with that (I'm guessing the "off" score). Even if you got a boost and it was working as well as a full core it wouldn't be more than 2x. There are a few applications that get a 30% or so boost but most are less than 5%. This is DVD recode? Explain how you run the test and I'll tell you how Conroe does. I have 6.6.
