AMD Radeon HD 5770 CrossFireX Performance Scaling

"Radeon HD5770 CrossFireXTM earns a Gold Tachometer Award, because it delivers an unprecedented level of performance at the $500 mark. Not only that, it's budget friendly in another way; you don't have to come up with all the cash up front. You can buy one card now, and have a guaranteed upgrade path. What makes this combination more worthy than CrossFireX combinations in the past is its scalability with first generation drivers. This is the first time an entirely new architecture has come out of the gate with this level of stability and performance in a multi-GPU arrangement."
