i have a geforce 6600 (bet u couldn't have guessed that one either, huh?) and I had contacted NVidia and they said I could monitor the temp and control the core clock speed from the setting s menu. Well I haven't gotten back with them and ran across this forum so I thought I would ask you. I have covered their desktop menu the XP device menu and hardware properties and have yet to find anything describing or controling these items. can you enlighten me please. Thanks JW
