Hey there guys, my new geforce gtx 260 just came in the mail, and I don't know what this cable is for. I've attached in image, the cable I'm talking about is second from the left, it's small and grey, with one end that plugs into the video card and another that plugs into two pins on the motherboard. There's an audio symbol where it plugs into the card, but to be honest I have no idea what this is for, I've never seen it. I like to take advantage of extra features, so if you could take a look at it that would be great. I've done some searching with google and wikipedia with no success so far.
Thanks
