It's not the same chipset at all Bladerunner, its the G92 whereas the GTS is the G80. The G92 is a 65nm chipset hence it running cooler and using less power, thus being able to run faster I guess.


). People say ATI drivers are crap, but they also say Nvidia drivers are crap... atleast, I can testify that my aging x800 pro still receives the occasional performance boost from installing new drivers, even though most/all efforts are concentrated on the higher end, so I'm actually pretty happy with ATI/AMD there.
Been a long time ATI and Nvidia user, and there are always similar problems that arise when using new drivers. Most of the time the only solution would be to roll-back to an older driver, since some drivers would have issues with a certain option in their 'control panel' or just have poor performance overall.
