ZDNet's come up with a software-based app to overclock processors on the Intel 5000 and 5400 chipsets, which (as of right now) is the Mac Pro and Xserve. Apparently ZDNet Clock is so good, the cheapest 2.8GHz Mac Pro outperforms the 3.2MHz Mac Pro, saving you $1600. You'll have to fiddle with the slider to get it customized for you, so don't think you can just drag it to the right and not have a crashfest on your hands. Hit up ZDNet to see the details. If you can get this to work right (and have enough cooling), it could be fantastic for heavy computational tasks. [ZDNet via Wired]
