Sadly it looks like, when overclocking is taken into account at least, a Q6600 will still be a better CPU than the Phenom II 940 and likely be $100 cheaper. Deneb doesn't come close to matching Yorkfield clock for clock and it does not match Kentsfield per clock either. A 3.6GHz Q6600 will be more than competitive with a 3.6-3.8GHz Phenom II 940.
