Multiple GPUs (2080ti,1080)? *NOT* running SLI for multiple Monitors? (4k, 2x 1440p)

[Nanofiber]

OK so I've got 3 Monitors, (Asus PG27UQ 4k 144hz) Monitor, (Asus PG279Q 1440p 144hz) Monitor, and (The Razer Raptor 27 1440p 144hz) Display all hooked up to a 2080ti, but with 1 gpu pushing that many pixels I was wondering if adding in like a 1080 to run both 1440p displays would take some of the load off for the 2080ti running 4k 144hz. Im new to these forums so I hope I posted this in the right spot 

 

 

2080ti GPU: 4k 120hz* (lMAO not 144hz LIES SCAM) ?
1080 GPU: 1440p 144hz, 1440p 144hz ?

I usually use the PG27UQ As my Primary display to play games with, leaving the other two for productivity, video and photo editing, (and like watching youtube :)))))).

From my experience, having multiple monitors hooked up, but not showing anything, doesn't impact performance at all. Does increase the GPU temps a bit.

 

But if you're gonna watch YouTube or whatever intensive on the secondary screen, a second GPU could help.

I don't have experience with setting up two different GPU's though...

 

But I have seen people run setups like this. For folding@home, mining, rendering, that sort of stuff.

having more than 1 gpu in there is bound to run into some bugs, and the 27uq will run 144hz (there's an oc option in the menus, turn that on first) if u lower it to 4:2:2 from 4:4:4 or RGB, but expect slight ghosting. 

 

I don't know if this applies to you but i've found that leaving gsync on lowers the gpu idle power usage for whatever reason, and if it stutters just make sure gsync is only for full screen apps.

 

The 2080 ti alone will be fine, probably better than 2080ti+1080

oke I will most likely hold off for now until I get further answers. but I just feel as if my 2080ti is getting held back by the other 2 displays so idk ¯\_(ツ)_/¯ 

but thanks for letting me now bout the 4:2:2 switch haha

huh ok thank you, I might try adding a 2nd card later down the line but I want to make sure that it would even work lmao.

You could try enabling the iGPU (if you're on Intel), plugging a panel or two into the motherboard & see how that works to start with. 

From my personal experience, multiple monitors & GPUs doesn't work as well as it should, especially with mixed refresh rates. Playing video of any kind on the other panel introduced bad FRAME PACING, (not to be confused with frames per second). It was bad enough for me that I stopped using a second monitor while streaming. Started using things like Xsplit GameCaster because everything I needed was overlay based on a single panel. This happened while using both AMD & Nvidia. 

That being said, I haven't added a second panel or GPU to my setup since before Windows 1803 (I think) and I heard there was supposed to be some tweaks coming in this dependant. So it might be better.

I never run multiple monitors on a single card unless it’s for surround. 

I prefer the card to be able to downclock. Especially if on air. 

I’d add another card.
