One should be ever booted and spurred and ready to depart - Montaigne
Nvidia reference cards are clocked at 500MHz core and 1600MHz while the new ones from Gainward should work at 550MHz+ for the core and 1760MHz+ for the memory.
The card will have the same cooler as the reference one but Gainward will provide a warranty for these overclocked cards. The overclocking era has just begun and the race is on and Gainward has an interesting marketing statement for this card. ยต
