Will having a second monitor decrease performance on Games?

[i7-6700K]

I was thinking of having a dual monitor setup. One monitor for gaming, and while gaming, have the second monitor output a browser, or steam. My question is will this decrease performance on my games? (i'm running on OC'ed R9 390 btw)

Yes a tiny bit but hardly anything.

With just a browser or non-demanding application running, it has no observable impact on performance. If you're going to be running a 1080P video on something like VLC, it has a small impact, then 1080P Youtube videos have a larger impact.

Thanks for the replies!

I had 3 montors not too long ago and only used the main one for gaming (different sizes and orientations made surround impossible). Out of curiosity I unplugged the two that I don't use for gaming and saw absolutely no difference in frame rate. I even ran GPU benchmarks and the difference was within margin of error.

Think of running an image on a regular monitor that moves a little here and there and add the game to it..

 

Your game won't feel any different so you have nothing to worry about. I do the same with Battlefield and there is a less than 5 frame difference.

I game with movies or videos playing in the background it's pretty much just a tiny bit of extra vram and 390 has more then enough
