Re: xfx 8800gts 320mb 500mhz
Overclocking barely poses any risk when done correctly. And another note, is that it doesn't take much life out of the card either, when running the card that high for everyday gaming.
Those clocks that you see, some are stable, some are not. Depends on your case's airflow. If you got it good, you can reach those speeds. 600 should be easy to get, with good airflow in the case.
