I just got a second card installed but when I try to game with it I always hit a CPU bottleneck. I haven't been able to get both of the cards very far past about 50% usage, which is quite ironically frustrating. In BF4 the cards stay about 40-50% usage, while the CPU is at around 50% useage and the FPS is very jagged around 30-50. Similar performance shows up in all graphics demanding games I have checked with as well.
