WorldBench
WorldBench uses scripting to step through a series of tasks in common Windows applications. It then produces an overall score.

Now here's an interesting result: the bottom three rungs in our WorldBench results are occupied by boards based on Intel's flagship X48 Express chipset. So much for a high-end performance advantage.

To be fair, only four points separate the fastest boards from the slowest here. The results are somewhat tainted by inconsistency in WorldBench's WinZip test, which seems to be affected by Vista's supposedly intelligent caching scheme. The Rampage Formula and X48T-DQ6 both turn in completion times in the WinZip test close to a minute slower than their competition for no apparent reason.

Gaming

Even at these relatively modest resolutions, games tend to be bound more by the graphics card than by a system's motherboard. The biggest gap in performance comes with Quake Wars, and even then, you'd be hard pressed to tell the difference between 119 and 130 frames per second.
