High frequencies probably means higher overclockability. Maybe the GF104 can become the new GTX 275?
Beside reducing performance Nvidia cuts GF100 more or less in half and this has a lot of positive side effects. The circuit becomes cheaper to make and the power consumption easier to handle. Thanks to 40 nanometer technology and a less complicated GPU the frequencies can be boosted a lot higher than with GF100. According sources GF104 will be capable of 900 MHz and up when overclocking, and even if we don't expect these kind of clocks from factory it bodes well for overclockers wanting to take a swing at Nvidia's new card.
