Re: Which should I do first?
The order does not matter, but I would recommend doing the video driver first, if only to save yourself some trouble if it doesn't work and you need to reinstall the OS. Video drivers are the most ornery, or have potential to be, anyways. The other stuff normally installs without issues.
