Think your gaming rig's impressive because it can run Metro: Last Light with maxed out settings at 60FPS? Well, Microsoft rounded up a trio of Sharp PN-K321 32-inch 4K monitors and wired them to a Windows 8 PC stuffed with three ASUS 7970 GPUs. The $17,000 experiment proved two things: Such tech is outside our price-range, and it takes a huge amount of support to get it working. For instance, before AMD wrote custom drivers to make Eyefinity and multi-stream transport play nicely together, the framerate was a meager 8FPS. It's worth noting that even after all that, demos only lasted a few minutes before the computer's power supply would conk out -- but maybe the kinks will be fixed in time for us to play Battlefield Bad Company 5 on it.
