The issue is the fact that AFR mode (alternate frame rendering) results in each card rendering one frame at a time, effectively using the framebuffer allocated to each card instead of doubling them up. This means that in memory limiting situations, you may get significant drops in minimum framerates while the average performance results will be much, much higher than with a single card. HOWEVER, in non memory bottlenecked situations, you will get amazing performance.
