Some of us own Macs so that we may compute in peace, away from the old world of tweaking unstable monster gaming PCs. Get back off the wagon with this Mac overclocking utility from ZDNet. Soon, there will doubtless be benchmarking software too, so that human-imperceptible performance differentials may be measured.
It's also a bit amusing how ZDNet reports something it did as an "exclusive." If you didn't get the exclusive, guys, something would have been very wrong.
