Nvidia NVS300 card with dual output lead

Hi I have obtained an nVidia nvs300 card as a cast off from my work, it has a one into two cable which serves 2 dvi monitors from a single port on the card. Has anyone used this before, is it 32bit/64bit particular? Is it likely to work with an AMD 64 bit system? At present I am running two identical monitors from the DVI and VGS ports. I would like to move to two dvi monitors set up for consistent resolution between the two. Hopefully yours Andrew Greig
