Since I moved I got rid of all my spare components and have tried to keep it that way by selling everything when I replace it. So my backup is the integrated graphics.
I have a 6870 laying around, I looked up how much it's worth these days. I think it was like $30. So I decided to just keep it, so I suppose that's my backup!
well basically the IGP until i can get a new card... or I could steel my wife's computer for a couple days it has a HD6850.. which is fine because basically all she does is play games on facebook w/ it near as I can tell. well and buy stuff from amazon..
