I was wondering if the DDR chipsets would support this new speed of FSB for the new P4's? Sounded like in reviews that I have read "some" of the 850 motherboards will. I am thinking about building a P4 rig to see what all the hype is about. I know the new P4's don't reach their full potential unless used with the new 1G Rambus. There is a new chipset out for this processor, but do you have to get a new board to support it? I think it would pretty lame if you did.
