I am building a new system with an ASUS P4C800E-Deluxe motherboard. I want to use my old video card, a GeForce 2 GTS, until I can get a new card. The ASUS manual says that only AGP video cards requiring 0.8 or 1.5 volts can be used with this motherboard. I have read that my GeForce 2 GTS is AGP 2x/4x compatible but AGP 2x is 3.3 volt and AGP 4x is 1.5 volts. Does anyone know how I can determine if my GeForce card is safe to use with my new ASUS P4C800 motherboard? I have checked the NVIDIA web site and read the AnandTech and Tom's Hardware reviews on the GeForce 2 GTS but they don't say anything about card voltages.
