So single card performance is not up the max possible.In multi-gpu scenario,2 cards are performing great due to present good optimizations in Catalysts for CF.
That doesn't even make sense. Dual performance is based on the performance of a single card. In what reviews have you ever seen two cards perform over twice as well as the single card? I've looked at hundreds of reviews and I've never seen scaling that was better than perfect.
