The 925XE is based on the well-known 925X, but finally introduces support for FSB1066. While a new Pentium 4 Extreme Edition at 3.46 GHz will be the only available processor for the time being, the new platform could have a long life expectancy -- it can host all the 600 and 700 series P4 processors, and likely will also run Intel's dual core models, too.
