Intel 845e chipset and GeForce 2 GTS?

I just purchased a Gigabyte GA-8IE motherboard, which is based on the Intel 845e chipset. According to the manual, it only supports AGP 4x 1.5V video cards. 3.3V cards will damage the motherboard. Unfortunately, I can’t find any easy way to determine what voltage my current video card is running.

Can anybody tell me if the GeForce 2 GTS cards run at 1.5V or 3.3V? They claim to be AGP 2.0 4x cards, but I know there are some 4x cards running at 3.3V.

Does anyone have a GeForce 2 GTS card running in an 845e motherboard?
