3D Mark feature tests
While the 6800 GS does better than Sapphire's X850XT PE in the single texturing test, cards manufactured by NVIDIA are left in the dust on the multi texturing benchmark.
6800 Ultra wins hands down. Also worth noting is the fact that the overclock adds 20 frames in this scenario.
Very even situation, the standard clocked 6800GS is a little behind compared to its opponents, but it makes up for it one overclocked, just crossing the finish line as number 1.
