What's more interesting is that system builders, who've built hundreds of systems, enough to get a fairly representative sample, are split on this issue, too. I don't doubt that on the whole, most of you on both sides have been honest and truthful. If you get nothing else out of this, understand that there are sincere, competent people out there who are getting quite different results than what you're getting. Sure, but it's not all of them. It's safe to say that much of the reason for different beliefs is that you just can't pick up relatively similiar statistical trends based on a small sample.
Nobody can determine that based on testing one or even a handful of boards.
You'd have to test hundreds of boards, maybe more like fifteen hundred setups, before you could say with a good degree of statistical certainty that there's any difference. When we get to CPUs, the differences are even tighter. You'd have to test many thousands of CPUs before you could definitively show a difference. Of course we can. That's far more arguable, at least under these kinds of circumstances.
