GeForce 6600 GT
The flagship of the middle-end line is GeForce 6600GT. The main differences between the 6600GT and the 6600 are, first of all, the memory standard used - GDDR3 is installed on the 6600GT; the nominal frequency of the GPU, which is 500MHz for the 6600GT versus 300MHz for the 6600; and support for NVIDIA SLI technology, which is present on the GeForce 6600GT.
