Ok bit of news from China... Nvidia will be releasing Mining Only GPUs soon... These will be GPUs without any display panels, no DP, no HDMI, no DVI... just a card and cooler. They will only be able to mine, they will not work for things such as playing games or rendering video, etc...
Just a heads up on whats to come... If your thinking of building an Nvidia mining rig now... might be best to wait...
