I know PCGH was done with one HD 5870 but even with the low minimum FPS the video looked smooth without any pauses or hard pauses as you described in your experience.
When I run my benchmarks I also had the PRAPS on and the minimum frames did show couple seconds at the begging of each run after that the frames were very close within the average FPS.
Now if you re trying to say PCGH didn't experience the problem since they didn't use any "form of ATi MGPU"
and you did. Why if you had all this problems with ATi MGPU you bought the third card, like that would fix the problem.
