Anyone else read Tom's article on the P4 vs. Athlon XP at very high speeds (3 GHz for the P4, 2GHz for the Athlon, IIRC). Seems the P4 does very well at higher clock speeds. I remember also reading an article (Toms again?) pointing out how RAMBUS memory tends to scale better than DDR. So perhaps the P4+Rambus will make for a nice combo >3GHz.
