ASUS has effectively made its i925X-based P5AD2 Premium board redundant with the newer P5AD2-E Premium. The latter carries all the feature nicities of the former but adds in support for 266MHz FSB CPUs. As described, not only is this beneficial from a complete processor support point of view, it also allows the enthusiast to be safe in the knowledge that 200MHz FSB Pentium 4s, which is the vast majority of Intel Pentium 4 chips out there, can be overclocked by at least 33% before the motherboard becomes the limiting factor.
