Jedi Academy is pretty hard on the processor, and the overclocked D 805 doesn't seem to gain as much over a stock D 805 as it does with other games. The stock Sempron meets the overclocked D 805 face-to-face.

No surprises here. Decent gaming performance when overclocked, but AMD chips rule here -- even the Sempron commands a small kingdom.
