Intel's first Kentsfield chip, the Core 2 Extreme QX6700, hit stores earlier this week with a clock speed of 2.66GHz. Rumors claim AMD's 4x4 processor kits will follow before Christmas with speeds between 2.6GHz and 3.0GHz. We'll have to see whether AMD can compete with the QX6700's current ~$1,100 price tag, though. AMD itself stated that 4x4 kits would launch "well below $1,000," but the price of 4x4 motherboards may be higher than that of their Kentsfield-compatible counterparts, especially if Asus does have exclusivity. Support for dual processors should add to the production cost of a board, and Asus' high-end enthusiast motherboards aren't typically known for their low prices.
