QFX vs Kentsfield - revisited

I mentioned it a few days ago, that many benchmark sites choose to run their benchmarks with an incapable operating system. The Inquirer wrote a nice article about different system concepts of QFX and Kentsfield and why the market will fall in favour of AMD´s concept of a Quad Core system. But at the end, it´s a question of workload which concept is better for you: Kentsfield, when you have a CPU bound workload, QFX when you have an everything-else-bound workload.
