Overclocking radeon 9500 pro
can be done with a software mod or can be done by flashing the bios which is unlocked.
I flashed my bios.
Afther this you need a software tool installed which allows you to shift up the frequency of the memory and/or the processor.
It won't be hard to find this software. I myself use radclock...it is small and simple.
Beware when you buy a radeon 9500 pro. Ask for the speed of the memory. Demand/ask for 3,3ns memory (or faster) which allow overclocking to (1000/3,3) 303 mhz.
Also would advice to buy heatsinks for the memory. MAkes the card more stable when overclcoked.
