While a "straight-up" comparison between the Intel and AMD platforms isn't really possible, this is as close as one can get, in my opinion. Motherboards.org does a really good job of it and has picked the parts with care so the benchmarks (under Windows) actually tell you somethings that can be considered factual. That's quite an accomplishment. Really!
If I could see a half-dozen of these done this well, I might begin to think I had a real basis for comparison.
