ADM still didn't get the crown, but I think they became much wiser in their pricing given their situation.
■Q9550 = 315$
■Q9450 = ???$ (being phased-out for the Q9400, not even on newegg anymore)
■Phenom II 940 = 275$
■Q9400 = 270$
■Q6600 = 190$
Intel is gradually pulling the plug on the Q6600 because, for it's price, it competes with it's newer Q9XXXs. Doing so they push people toward the Q9XXXs. Given the ~20% difference in price with the Q9550, a 10-15% performance difference is still a reasonable $/performance trade-off.
It wouldn't be worth it to change from a P35/P45 board that support the Q9XXXs, but if you have to change board to have a quad and aren't a hardcore performance addict, then I think the Phenom 2 is a great option.
One thing I would like to know is how far the 920/940 can be OCed, the 940 being a BE should have an unlocked multiplier, right? Moreover, how big of an impact the AM3 socket will have? I think overall many things are still unknown, but I'm glad AMD is trying hard ... that is how they started after all
