One thing that sometimes bugs me is that all these benchmarking sites don't run the exact same benchmarks, there's always something a little different. So if you want to compare the score of one machine as tested at site #1 with the score of a different machine at site #2, you can't. It wouldn't be an apples to apples comparison. But I did observe something interesting in the case of the IDF results. The following two links each contain benchmark results for Windows Media Encoder 9. One of them is for THG's review of the FX-60, and includes the OC'ed version at 2.8GHz. The other is anandtech's benchmark run at IDF for the same chip. I'm amazed that both tests came up with the same result: 75 seconds. So this could be a good sign that the IDF numbers are on the up and up, or at least they didn't cripple the FX60.
