Something to this effect has been brought up on here before, but this looks interesting.

"Whereas most current graphics cards can only drive a pair of displays, AMD has put some special sauce in its next-generation DirectX 11 GPUs to enable support for a whopping six monitors. There's no catch about supported resolutions, either. At an event yesterday, AMD demonstrated a single next-gen Radeon driving six 30" Dell monitors, each with a resolution of 2560x1600, hooked up via DisplayPort. Total resolution: 7680x3200 (or 24.6 megapixels). AMD's drivers present this setup as a single monitor to Windows, so in theory, games don't need to be updated to support it. AMD showed off Dead Space, Left 4 Dead, World of Warcraft, and DiRT 2 running at playable frame rates on the six displays."

Excerpt copy/pasted from the slashdot article that got my attention, and here's a link to the actual article that has photos.

All I can say is ... I know some multiboxers that would love to use a 7680x3200 display that runs that fast from one PC.
