80727!! I'm happy to support BTS but I have to say that charging your credit card immediately is really a poor way of doing things. You guys need a modern ordering system if yours forces you to work this way.
Definitely return it. AGP is a much faster connection for the video card to the rest of the computer. If you can, exchange it for a non-GF4 MX card. A good value now is any GF4 Ti200.
