I currently have a standard $650 desktop computer with integrated Radeon HD 4200 graphics. I have two 6950's awaiting crossfire for my new build, but while my build is on hold I was wondering how to use one 6950 in my current computer while I wait. As far as I know I have to disable the 4200, but I don't know where exactly to plug in the 6950, and how/when to disable the 4200. Also would it be as easy to switch back to how it was when I take the 6950 back out for my new build and activate the 4200 again. If anyone understands what I mean I appreciate any help.
