HardOCP has taken a look at the performance of ATI's Eyefinity technology across the entire line of ATI Radeon HD 5000 series graphics cards. You can check out the review over here.
We’ve written several evaluations on Eyefinity since its introduction, giving you a glimpse and trying to relate to you what the gameplay experience is like. We even held a special event in concert with AMD to demonstrate this awesome gaming technology. Through all of this, we haven’t yet evaluated the performance associated with running such high resolutions down the line of AMD video cards. This evaluation is an attempt to relate to you performance on the most common configuration we have come across with AMD’s ATI Radeon Eyefinity technology.
