I bought a ATI Expert 98 video card at a local computor store. I told them I needed a pci card. When I went to open package when I got home it was a agp card so I went back to the store. They told me it would work in pci slot but from what I understand it will not. I have never upgraded a video card before. My system does not have a agp port on motherboard. I have not tried installing card because I do not want to mess any thing up. I wonder who is correct, me or the store?
