Kyle Bennet over at HardOCP has taken a couple of snaps of two different Barcelona based systems at an event in California. There's one single CPU and one dual CPU system pictured.
Both systems are powered by a quad core AMD Barcelona processor, although no clock speeds were given for either system. According to the post, the dual quad core system was encoding a 1080p trailer of Spiderman 3 into H.264 and was doing this close to real time.
Both systems also had a Radeon HD 2900XT graphics card in them.

On a funny side note, it seems like the Chinese language site Hardspell is trying to pass Kyle Bennet as AMD's CTO Phil Hester. Babelfished version here
