The card for serious business can game too.
We caught some video of two demonstrations of the AMD W9000 at SIGGRAPH 2012:
This video wall was on the side of the AMD booth. It was being fed 4K resolution images by a single AMD W9000 workstation GPU, implemented as a single Eyefinity group.
And inside, AMD used a W9000 to drive five displays for a flight simulator- two large displays covering an arced field of view for the main viewpoint, and three smaller displays covering instrumentation and the lower window of the cockpit. You’ll notice that when the person uses the hat on the controller to look sideways, several of the displays pivot in synchronization -- pretty good performance across multiple displays too.
