On TomsHardware.de (Germany) I found yersterday an comparision between an Dual (2xdual) Woodcrest system and one powered by an AMD Opteron.

The article says, the Woodcrest-system was delivered by INTEL for testing.
Given the rumors that Apple had outsourced the developement of the MacPro to Intel, and given the similarities of the "air-condition" in both the G5 PowerMac and this prototype, it COULD be the next MacPro in an ugly computercase. I am pretty shure about it, because INTEL founded an research-departement right there in Munic, where also TomsHardware is located.
