The problem comes from inefficiencies of Crossfire/SLI handling multiple GPUs. A single GPU will always provide its peak performance.

This image sums it up best. Vertical variance = micro-stuttering. Notice how it's significantly less on the single-GPU 6970? Even though the 6990 is performing better, it's stuttering like crazy. A consistent, somewhat longer time frame is more important than varying, faster time frame performance.
