Supreme Commander
This game is multithreaded and can actually take advantage of more than two processor cores, making it a rare commodity indeed. We tested performance using Supreme Commander's very nice built-in benchmark, which plays back a test game and reports detailed performance results afterward. We launched the benchmark by running the game with the "/map perftest /nosound" options. (Normally, we prefer to test games with audio enabled, but we made an exception here.) We tested at 1024x768 resolution with the game's default quality settings.

Supreme Commander's built-in benchmark breaks down its results into several major categories: running the game's simulation, rendering the game's graphics, and a composite score that's simply comprised of the other two. The performance test also reports good ol' frame rates, so we've included those, as well.

The faster bus on the E6750 confers only a minuscule advantage over the E6700 in Supreme Commander, another game whose performance doesn't seem to be especially CPU-bound with today's processors. That small boost is all the E6750 needs to place it near the top of the pack of dual-core processors, just below the Core 2 Extreme X6800 and Intel's two quad-core Extreme Edition processors.
