The i7-3930K better perform much above it, as its price is almost 4x as the AMD CPU. ($600 vs $175) |

Indeed, some numbers for comparison would be nice.

Maybe you missed that I'm running Linux on my box.
So no Fritz Benchmark. Thank you anyway.

Well, it is nice to have 8 cores on one die. Unfortunately, Bulldozer CPUs are running on the hotter side. So you definitely need a very good cooling.
But the speed at 4 GHz is better than I expected. I read several reviews about the Bulldozers and their poor performance, especially with 1 core.
Of course, an Intel 8 core system is faster. But you have to spend much more bucks, too.
