The Mother Nature test is a big problem for any graphics card that is poor at processing pixel shaders version 2.0. Sky-high frequencies can’t help GeForce FX 5950 Ultra here. Extreme overclocking brings in little advantage again.

Overclocking adds some speed to the cards when FSAA and anisotropic filtering are on, but they still perform slowly. Through extreme overclocking RADEON 9800 XT managed to hit the 30fps mark, though.
