"For those of us that feel that any of the GeForce2 Ultra cards released now are out of financial reach, there are some manufacturers building cards around nVIDIA's GeForce2 GTS Pro. Our example today is from Guillemot/Hercules - the 3D Prophet II GTS Pro 64MB. This is a speedier version of the regular GeForce2 GTS, with a 200MHz core clock and a 200MHz RAM clock (400MHz effective with DDR RAM). This means that the GeForce2 GTS Pro runs at the same speeds as the GeForce2 Ultra, but how close can it get using the older chip design?"
