Will my Second Monitor Take Away From my Primary Gaming Monitor During Gameplay?

I have a MSI GTX 780 and when I am gaming I use a 26" 1200p monitor at 60Hz (I know I need to upgrade). Question; will my second screen (1280x1024) take away graphics resources even though it isn't active but still shows the desktop? Since it is still putting out 1,310,720 pixels does this eat into my GPU's output? Not that it matters terribly for my particular setup but it's more of a fundamental/philosophical question related to how this operates. I am asking because it could mean more fps if it does and this could be useful but does anyone know the answer to this? Thanks and I hope to get at least a few responses even if just to verify others. For the record I also have a i7 Ivy, a MSI gaming series motherboard and a 750 watt PSU from Corsair.

Short answer: No.

I run 3x 1080p monitors under a single 780Ti, ran benchmarks with and without the 2 extra monitors attached and the difference was about 1-2fps. Now, if you plan to watch high def videos while gaming that is another story, watching 1080p while playing acreed4 my FPS drops from ~50 to ~20. So, if the extra monitor is just going to be idle, I doubt you would notice anything, especially due to the low resolution.

Taking into account the GPU you have, the fact that the Second Screen is Idle, and the fact that it has such a low resolution, it is such an unnoticeable amount of change that you have nothing to deal with. If you run the benchmarks you'll see a performance gain of maybe 1-3 FPS.

Thanks for the responses. So if it is idle than likely not a big difference but still some affect. So there is nothing funneling all the resources into one monitor while gaming. That is interesting to me.
