Will running 2 monitors off one card decrease fps?

[MexicanAnimal]

The title pretty much says it all, I have one 1440p display and also a 1080p, but I was wondering if running them off the same card would decrease performance on my main monitor, the 1440p one, that's where I'll be playing all my games.

 

Note - My GPU is a 780

 

Thanks!

Not unless yo are gaming on both. At most 1% or 2%

No you wouldn't loose fps because your 2nd monitor isn't running a game just beings used for light task.

The general consensus is no, however I have never tried it. I doubt there would be any difference in actual usage and fps difference.

 

However I do want to test the vram usage and see the difference in usage with one and two displays.

Yeah, I will just be using the 2nd monitor for browsing, or watching videos, or going on the Linus forums while I've got the 1440p one running a game. So I won't lose a substantial amount of performace?

No. I see no effects gaming on one screen with two monitors.

No there shouldn't be. although youtube did have an effect on my ram usage though.

RAM usage or VRAM Usage? Because in terms of system memory I have 16 gigs

RAM i have 8gigs. I haven't tested the vram although I'm sure someone has already.

I have, never noticed a difference in performance.

if you have a modern core i CPU you should be able to use intel HD graphics to power a monitor and dedicated card for another. I would plug the 1440p to your dedicated gpu and the 1080p into your intel gpu.

[DaMagicalManiac]

Nope (at worst it might use like 2% of your gpu memory, if you're worried use on-board graphics)

Not that I know of. There is a performance difference within Windows in both AMD and Nvidia cards that given a keen eye you'll notice but its not measurable in any games I have tried with it on and off.
