since when? I mean think about what you're saying: 3-4 times? Under what benchmark? Are you talking about synthetic benchmark "points" or are we talking about real-world applications?
Because even the most powerful Core 2 Extremes are MAYBE 3 times faster than a Sempron 2800+ when transcoding a DVD9 to DVD5.
Which by the way, the 6400+ beat the Q6600 in this benchmark.
You scroll through the list of benchmarks used on that site (I found it very helpful when choosing a processor). Now try finding a benchmark where the Q6600 is 3-4 times more powerful than the 6400+.
And the 6400 is also cheaper FTW.
