| It depends on the card, the cooling, and the voltage.
The 6800GS is an NV40 on AGP cards, and is therefore a 130nm 16 pipe card.
It is the same chip used in the 6800 Ultra, which ran at 400Mhz standard.
As a general rule of thumb, 400-420Mhz is to be expected of one of these cards, with 420-440 considered good, and 440+ considered very good.
I run a lapped and polished heatsink, with a quality arctic silver 5 thermal paste job, in a very good case, with an Ultra Extreme (+0.1V) BIOS. This gives me between 450-465 depending on the driver in use.
With a heavy volt mod, and watercooling, an NV40 can run into 500+ territory without much effort.
What have you done so far with your card? (unlocking, overclocking, volt mods, cooling, drivers)
