how do i check the voltage rating of my video card. Whenever I use my GEForce 6200 on my ASUS P5VDC-MX motherboard, the screen is flickerish and the card is too hot when I touch it. My motherboard has a limit of 1.5V. Are the new NVIDIA cards needs more voltage or my motherboard is just not compatible with the card I bought. Can you suggest an NVIDIA card that is compatible with my motherboard? I need GEForce 6 or higher for me to play VT3 thanks!
