One of big concerns about the Windows 8 user interface is the GPU acceleration on multi-display configurations. During the AFDS 2012, AMD solved its approach to this dilemma; new Eyefinity driver functionality expands the GPU acceleration from single to multiple displays, and even accelerating applications and the user interface itself across multiple displays.
You can stretch the application through three displays and it will receive the same level of acceleration as it was running on a single screen. If you recall, Windows 7 or earlier Windows did not enable seamless operation on multiple displays, and running for example, a TV stream split between the two displays would result in a one display having a black window.
The second generation Eyefinity, which debuted with 28m Southern Islands GPUs enabled acceleration for multiple app windows, which should guarantee a very smooth experience. You can see our video above.
