Just a quick note. Recently Xinet Benchmarked a group of the leading server setups on the market. Included were the Xserve, and the Dual G4 Powermac.

Surprise, surprise, the Xserve was the best performer in the 2 processor crowd, and actually performed better in Photoshop open tests than some of the 4, and even 8 processor units.

Now, what do you know about that?
