Geforce 9500gt and Nforce 630i compatible?

My motherboard is a Geforce 7100 / nforce 630i and I'm planning to buy a video card which is a Palit Geforce 9500gt 1gb 128bit DDR2. I dunno if it'll fit in and be compatible. Please tell me if it will as soon as possible. And a quick explanation please, and adding a link would be great.
