Triple Monitor problem

[Lethal_Garu]

Like the title says, I have a problem with adding a third monitor to my set up. Gaming in 2 monitors, I hardly see any FPS drops when in 1080p in one monitor, and other monitor is idled at the desktop with nothing running on it, however when I add a third monitor, I experience huge FPS drops up to 30-40 fps in certain games when gaming in 1080p in my main monitor and the other two monitors on idle. No idea what could cause that huge amount of FPS drops when the other monitor's are just idled at the desktop background with no other windows, browsers, etc running while gaming on the main monitor at 1080p. Just to clarify again, I am NOT gaming on all 3 monitors, just ONE monitor at 1080p while the other two have nothing on it, just idled at desktop background.

 

System specs:

CPU: AMD FX 8350 OC'ed at 4.5ghz w/Cooler Master 212 Evo

If these make any differences, but it shouldn't I think:

well something i figured out a while back was that each monitor connected to your system still uses memory on your gpu. i noticed this with my sli system with triple 1440p. one card would constantly have the memory clock maxed and used more memory. while the other didnt use any. then i found out that the clock was bound to the amount of monitors you have plugged in and if you removed them the clock would drop. maybe something like this is happening to you but idk... you do have a 1070 so it shouldnt be impacting performance... well not that much anyway

What would be the best way to check for this?
