With the launch of AMD's Radeon HD 4870 X2 flagship knocking at the front door, a couple of hardware sites have managed to get their hands on early engineering samples of the card and post preliminary results, dropping a hint at what's coming next month. From what I saw today, AnandTech and [H]ard|OCP are the first two web sites to drop unofficial benchmark results. PC Perspective and The Tech Report are also among these sites. To make their previews even more interesting they have added performance results from GeForce GTX 280 in SLI and other popular cards that can work in pairs. Please let us know what you think about ATI's fastest single card.
