I am getting 670/800(1600) from my:
Gainward GeForce 7600GT 256MB Golden Sample card.
It has a huge passive heatsink on it.
I put a 80mm fan on top of it.
I am now thinking of volt modding it to go higher.

However my card was built with overclocking in mind.
You might get 620-640 / 740-770
Bump up the settings, and try running a graphic intensive game. If it freezes, you have OC too much. Reboot, and lower settings.

It's quite simple really, all it requires is patience.
