Usually hidden in the depths of the Driver disc there will be an overclocking utility. This will do the stuff for you and probably warn you of the consequencies of pushing it too far. There certainly is with MSI and 3D Power cards. I would imagine the same will be true with Radeon. To be honest though you might not notice a great deal of difference in frame rates. Nice though a 9000 64mb is you may need to upgrade to get the frame rate you want. Also of importance is the version of Direct X supported. Your card might even be just Direct X7 in which case you'll miss a fair deal of graphic goodies. Frame rate isn't everything. Over 30fps is just bragging!!!
