Skuzzy,
Out of curiosity, do you have a simple setup and script I could use to run the same render you do and get a little comparo on the speed? I'm running an X2 4400.
I haven't used povray for a while though, so I'd need instructions on how to get a run that can be compared. For example, how do you set it up to use both cores?
Anyhow, let me know if that's something you could send me so I could make a comparo run.
