So I hate to be that guy who asks for help on his very first post, but desperation>pride right about now. I bought a 6870, and installed it to find that I can hear windows booting, but I get nuthin in the way of video. I have swapped cards, manufacturers, monitors, and on and on. I have RMAed a few times. But that is not why I am here. I am needing to upgrade, and since I am, I want to make sure I get a setup that will dance with this card. If anyone is running a 6870, please tell me what kind of mainboard and processor you have.
