How much of a decrease in FPS per monitor?

[Henleyz]

I've never actually knew the proper estimation but I know some exists, I already have 2 hooked up to my 780ti, getting another right now. So what are we looking at here?

[Tea1337]

I''m guessing another 1/6th less FPS per monitor added, probably more.

[Benjio]

Well it's going to be 50% more pixels to drive, I'm not sure if that exactly scales to fps though. I'd say its going to be a lot more than 1/6 less. And I'm assuming you're going to be having the game on all three monitors?

If the monitors are just displaying an idle desktop, there's really no difference at all. The only difference you would see is if you were running programs that use GPU power alongside your game.

Would be interesting to know if you are going to game on all three or just game on 1 and have the other 2 for workstation purposes. But in your sig I see this is a 144Hz monitor. If you are going to game on three of those you probably will have to buy another GTX 780Ti in order to get good FPS.

 

I use 2 monitors. A 27" Dell 1440p @ 60 Hz for gaming (will be replaced with the Asus Rog Swift) and a Samsung 23.4 1080p. But the second monitor is just as side gimmick. I use it to surf or watch youtube clips while gaming or monitor my hardware with it. In terms of performance, I don´t even feel that it´s there. Didn´t run specific benchmarks for that but I think it isn´t really a big deal.

if gaming on multiple the single monitor performance can probably just be divided by number of monitors although it's not really a accurate representation. 

 

If only one monitor is running a game and the other(s) is just displaying say Google tabs or your steam library performance decrease is very unlikely to be found, any real decrease will come from you have running in the other monitor(s). I can't run BF4 on one screen and the BF4 active battlelog map of the multiplayer game im playing on- the extra load of the live map is too much more for my i5 to handle and so my BF4 lags quite a bit.

Sorry all, I should of added that I will be gaming on my 144hz monitor, while the other 2 will have Facebook or Youtube or something along those lines open.

Youtube might impact the performance depending on the rig, hard to say if you will see a difference especially with your PC, maybe 10% just an estimate from my set up but my i5 can really be downer in some games with youtube open and playing a video.

the fps won't change*.

 

*well, not by a meaningful amount anyway. An idle desktop won't affect it at all, so play a youtube video on one of the two monitors while the other is gaming and see what your fps is. It will be pretty much identical.

In that case I don´t see any issues at all that you will loose a lot of performance. You should be fine. And anyways you will stress with that multi tasking more your CPU than you GPU. But with a 4.4 GHz clocked 4770K no problem .

Perfect thanks for the information guys!
