ScienceMark 2.0, Pifast
AMD's S939 CPUs have made motherboard performance evaluation a moot point. Look how close both S939 SLI boards are to one another when judged in terms of memory bandwidth and access latency.
The same goes for Pifast. Both S939 boards run at identical speeds, so the lack of performance deviation, given identical components and memory timings, is no great surprise.
