Hello to everyone, Well here is my prob. I have a dell inspiron 530 with vista 64 with a 20 inch flat monitor very basic. I bought a GeForce 9600gso 768 graphics card to watch movies and I don't do any gameing at all. I opned it up and read everything and now I need a new power supply. So I orderd 500-watt stealth xstream power suplly form dell, Will this work? I have not installed the card yet, Should I install power supply first or the card? And is it hard to install power supply? Can anyone Help? Thanks to all!! Rick
