PCPER.com: 5 GHZ+ Phenom II Overclock on Dry Ice, 6Ghz on LN2

Actually Q9550 is interesting for upgrade but for a new build i7 920 strongly concurrence it.
After that without knowing PII price it's hard to speculate. We speak alot about PII 940 BE but if PII 920 BE it's price around 200€ and can match (approx. 5%) Yorkfield clock for clock that's can be the real deal.

Yes, for a new build, the i920 is definitely the cpu to get at the moment since it's in the same price bracket as the Q9550, but the Q9550 has the same advantage as PII, it is a drop-in upgrade. You wouldn't need a new board and DDR3.
