A couple of weeks ago, while examining NVIDIA's GeForce 8800 GT performance in an SLI configuration, we tentatively labelled 2008 as the year of the multi-GPU configuration, and if ever there was a more timely hardware launch to back up that premise, this is it. While ATI's RV670 architecture has won them back at least some ground in their price and/or performance war over NVIDIA, the Radeon HD 3870 still doesn't hold sufficient performance to allow for launching a serious assault on the single graphics board performance crown. Enter the Radeon HD 3870 X2 graphics part which in essence is two RV670 GPU's which are acting in a CrossFire configuration on a single graphics board. - Elite Bastards
