I have just purchased an ASUS STRIX 980Ti to replace 1 off my 2x SLI GTX 580's after a failure on 1 off the cards (Just need to figure out which GPU failed now as I mixed them up).

I am running a 3 monitor setup, each monitor individually 1920x1080 @ 120hz (non-surround).

I mostly use the machine for work and the occasional Dota 2 & XCom 2 gaming session. All gaming done single screen with some youtube video or webpage open on the other 2 monitors.

My question is what is the best way to connect the 980Ti and remaining GTX580 to my monitors? I have had a look around and cannot seem to find a concise answer for my setup, they mostly focus on surround displays.

    1. Connect the 2 supplementary displays to the GTX580 and the main display to the 980Ti with SLI (not sure if that is even possible).

    2. Connect the 2 supplementary displays to the GTX580 and the main display to the 980Ti without SLI.

    3. Connect all 3 displays to the 980Ti and use the GTX580 as a physx processor.

    4. Connect all 3 displays to the 980Ti and remove the GTX580.

    5. Some combination I have missed.

Any helps is much appreciated.

Thanks

You can't connect a 980 Ti and an 580 with SLI. Connect the main screen to the 980 Ti hat you use for games, the others to the 580 is what I would do.
