That has to be the worse review article i have ever seen.
The Core 2 Quad QX6700 runs at 2.66GHz at stock speed, and I suspect that AMD will price the Phenom 9900 below the QX6700's current $949 price tag.
update: A reader pointed out that the Core 2 Quad E6700 running at 2.66GHz is available for $560
Fortunately it looks like the Phenom 9900 AMD sent us is a newer stepping - B2 to be precise - and even though it is not the fabled B3 stepping that will fix TLB erratum, it does seem to have opened up some extra "elbow" room.
Taking from the 1st and last page of that article
