2 GPU's, 3 monitors

[Micky123]

Hi guys, ok :

 

I am currently running 2 x 1920 x 1200 monitors off a Evga gtx 1080 sc which is absolutely fine.  I want to buy a 2560 x 1440 as my main monitor for gaming and use the spare 1200's for having a film shown and the other for twitch tv/browsing etc.  Can i buy a cheaper gpu to soley run the spare 1200's and then dedicate the 1080sc for my main 1440p?

 

Spoken in depth to evga and he suggests testing it first and that they need to share the same driver.

 

Any feedback would be fantastic.

 

Regards

Why would you need to do that?

Yeah, just run all 3 off the SC.

You can probably do that and it'll probably work.

 

But why? Having the GPU drive the other monitors while you game is going to take an insignificant amount of GPU power. Playing back a video or powering a web browser doesn't use much power for a modern GPU.

To answer your question: Yes, i believe you can do so, as long as (as EVGA has said) they can use the same drivers. Of course if you use an AMD card, the drivers won't have to be the same.

 

That being said, I would agree with the others above me, and suggest that you run all of the monitors off of your current GPU just to see how it fares. Alternatively, if you have an Intel cpu, you may be able to enable the igpu and use it instead.

I was told by Evga that running 2 1920x1200 monitors accounts to about 20% of the gpu, if i want to run the 1440p at max i will lose that 20% on gaming.  Not sure if its true, just wanted the max fps on the 1440p.

 

Just thought an easy option was to buy a cheap gpu to run the other 2 monitors.  I have never tried it and am a little apprehensive.

Frankly I would not trust their 20% figure - they might just be trying to push you into buying another EVGA card

 

I would test, and if you find performance is impacted enough, then buy a second GPU.

Thankyou very much for the replies, I will order the monitor and indeed test it. 

 

Thanks again
