AM3 is sompething i called "hardware tweakable". Playing with memory timing and bclk can help you more than software tweaking.
But AM3 could be fun if we had a real skill based benchmarks, like Gorgioprimo said. Something like Spi 8/16/32M...Only 1M and AM3 is not a good choice fur such a contest i think.

BTW, we'll see it in munich, a lot of things can be changed...
