Before we get to the benchmarks let me give you some background on the card. The 6600 series of graphics cards are based on the NV43 GPU. This is basically the little sister GPU of the ever so powerful NV40 or 6800 Series. The NV43 GPU is 8 Pixel Pipeline GPU with 3 3.0 vertex shaders and 1 3.0 pixel shader. The GPU core speed is 500 Mhz while the ram is at 1000 Mhz. The only real difference between the GT and the regular 6600 is the clock speeds. I wonder if I was to overclock a 6600 regular to the same speed as a GT if it would perform the same. I will save that for another day and article.
