My understanding is that because the 3dNow accelerates floating point
(unlike mmx, which helps integer math) not much could be done with it :(. 

However (and I really like this idea) because 3dNow is a separate pipeline,
it's been theorized that integer math could be simulated with the 3dNow's
floating point instructions, yielding a slight keyrate increase :).

PS Any word on the Athlon core?
