If anybody has this card or is simply interested, here are my results of overlcocking it. Test computer -P4 2.4Ghz -512MB DDR333 -PowerColor Radeon 9600 PRO 256MB - speed: 400 core/2*200 memory(stock) -Windows XP Pro (best one for testing in my opinion) -Newest Catalyst drivers from www.ati.com Achieved results - Core: 448Mhz - Memory: 2*241Mhz If either one of those was raised by a small amount, it wouldn't work well anymore. The overclock gave me about 10FPS gain on most of the tests I ran, on other ones the gain was smaller. Pixel Shader was the most noticable speed increase. Also the fill rate increased by a nice number. Overall, Im very happy with the result of the overclock. I know this isn't the best card, considering the speed of memory was lowered by 2*100 than the Radeon 9600 PRO "Built By" ATI, but still its good for now. No additional cooling was used.
