I'm not very knowledgeable about hardware, so I thought it would be safer to ask here
My boyfriend just bought an computer and I was wondering if I can upgrade the video card in it. It's running an AMD Phenom 8450 Triple Core right now with a Geforce 9100.
I was looking at maybe upgrading the video to an ATI Radeon HD4670 or something similar, but I'm not sure how to tell what is compatible and what isn't.
