I wouldn't rate how good a CPU is on how it does on superpi. Oooo goody, intel's CPUs can calculate pi faster, whoop-de-do, who gives a crap. I'm interested in the overall total performance. And I'm waiting until release to believe too much about it, a few benchmarks here and there with a lack of total system specs isn't very helpful to me.

Now I guess if calculating pi to the nth digit is your thing then whatever, do what you want.
