someone said the old macpro 2.66 has 2 FSB at a lower speed then new mac pro only shares 1 FSB for the chipset, does this make the older mac pro better?
While Apple has standardized on 8-Core Mac Pros as the "base" model, they actually do offer a single 2.8GHz Quad-Core CPU Mac Pro option for $2299.
Just a note for all you out there, this means that the new 2.8 GHz "quad-core" model has a single four core processor sharing a single 1600 MHz bus, whereas the previous-generation "quad-core" models had two dual-core processors on two separate 1333 MHz busses. This means that for bus-intensive, multi-threaded operations, the old models will perform better. Yes, even the old 2.66 GHz model will likely be able to outrun the new 2.8 GHz model.
