"The GeForce GTX 260 Core 216 does, without a doubt, improve performance over the original GeForce GTX 260 thanks to the additional 24 shaders that have been added to the graphics card. By increasing the number of shaders from 192 to 216 (a 12.5% increase) performance improvements were seen, but no where near the 12.5% that one might expect and this is on an overclocked version of the card!"
