There's nothing that says that the FSB _has_ to be half of the CPU speed, it just tends to be that way in the Apple product line. It all depends on the clocking. You can have a 2:1 or 3:1 or 5:2 or whatever. If you look at Pentium or AMD CPUs and FSB speed, there's hardly a 2:1 to be seen. 3.4Ghz P4s don't run a 1.8Ghz FSB. gretchen
