You can safely assume that the following rule is valid:

P4 x .6 = AMD64 Ghz

examples:  P4 @ 3 Ghz = AMD64 @ 1.8 Ghz, or P4 @ 2.4 Ghz = AMD64 @ 1.44 Ghz

Regarding the 2.4 Ghz AMD64 that you plan to buy, it would turn out that only a
(non-existant as yet) P4 running at 4 Ghz would meet the equation.

Simply put, an AMD64 2.4 Ghz is as fast for chess as a P4 @ 4Ghz, and quite
often it is as fast as a dual Xeon 2.4 (most notably running Shredder 9).

All this holds true for 32 bit systems, but a 64 bit OS would lead to Hyatt's
idea that a single AMD64 would be almost twice as fast as a 2.8 dual Xeon.


I hope that this detailed information will help you to decide which way to go.
