Got me one of those, and I must say I'm utterly impressed !

For my applications, performance of my X2 4200+ is approximately that of a virtual Athlon64 6000+ (comparing it to a single Venice core Athlon64), much higher than its conservative rating

Best of all, the entire System runs under full CPU load at a mere 115W (using a Voodoo Rush in it), in idle without Cool&Quiet it's about 77W.

With C&Q enabled, that box would likely be down to 60W in idle, absolutely amazing...
