Well, I'm certainly not going to bring up Intel's dual core CPUs, coming in 2005 and beyond...
...but instead of ranting, why don't you forward a hint at a solution? Yours is getting tiring too.
Intel specs seems to mention something about a "correction factor" to the TTV: do you know anything about it?
In the mean time, I'm in contact with Intel, about the TTV. Now to see if I can get something useful out of them...
