I can overclock my GeForce3 to 225/506 with stock cooling and it runs perfectly. If I get a Zalman ZM80C-HP Heatpipe VGA Cooler with a ZM-OP1 80mm Noiseless Fan how much higher clock speeds can I attain? This would cost about 60$ canadian, and I would hope I could get clocks at around 300/600. Do you guys think that is possible?
