It isn't the second monitor that is/may cause lower FPS but the watching of youtube on the second while playing. That causes the card to run at lower clocks, part of UVD, Unified Video Decoder - Wikipedia, the free encyclopedia
which are lower than the the full clock speeds. AMD cards have three different power states,
1. Low or idle where the clocks are at their minimum (100 core and 150 memory in the case of my 6850).
2. UVD which is somewhere between low and full.
3. Full, which is whatever the card is designed to run at.
The problem with youtube and running it on a second monitor while gaming is it causing the card to run in UVD power state, thereby causing a drop in FPS while gaming. No need to turn off or disable the second if you don't have youtube running as the card will then run at its full power state, and if there is any performance difference it will only be a couple of FPS if that.
