VR Zone has a bit of information about ATI Eyefinity, a new technology that will be part of the Radeon HD 5800 series:
It allows you to extend your game view across 3 displays like the Matrox TripleHead2Go except that it gonna be much more powerful. That's over 12 megapixels at 2560 x 1600 resolution for the ultimate gaming experience. It is ideal for flight sim, racing games, role paying games, real-time strategy, first-person shooter and even multimedia apps. So how powerful exactly this card is?
