Hello, I know there has been some discussion on very similar topics and have used the search feature, but none exactly match my topic.

Currently I’m using two superblocked EVGA Nvidia ACX GTX980 4G in SLI.

I was thinking of upgrading to the ROG Strix GTX-1080 O8G – Gaming.

The only game I’m interested in running is The Witcher 3: The Wild Hunt.

Would I be better off with this new card or keeping the old two? Money isn’t a factor in this decision for me?

Any help or advice would be greatly appreciated. Thank you.

You're confusing two sides of the same coin for two separate coins ;) What I was discussing wasn't average FPS, just min FPS/stutter. In general, a single card will give you more consistent results than SLI or CF. Unfortunately there aren't many SLI tests on the game that actually break down the specifics.

For Witcher 3, not much difference in total FPS. But that's because CDPR has probably the best developers around. Most games won't have as good of SLI scaling.

If you're playing at 1440p or less, I doubt that even min fps/stuttering will be noticeable in W3. At 4K you might...

I haven't tried it to compare stutter but if you don't observe any issues then I wouldn't bother. Here's a test:

http://www.gamersnexus.net/guides/2246-gtx-970-sli-vs-gtx-980-ti

"The Witcher 3 produces the biggest advantage for SLI, with the 2x 970s running 30.07% faster than the GTX 980 Ti at 1440p. That and the general low FPS improvement over the 980 Ti makes The Witcher 3 significantly more playable on the 2x 970s at this resolution. 4K is pretty rough across the board, but the dual cards do retain a technical lead (19.7%), despite neither configuration being what we'd consider 'playable' at Ultra.

The Witcher 3 also produces solid scaling numbers for SLI. There's a 50% performance gain over a single card at 1440p, or 47.62% at 4K."

With THIS: https://www.techpowerup.com/reviews/NVIDIA/GeForce_GTX_1080/22.html

A 50% gain puts you at 64FPS (vs 73FPS for GTX1080) however the GTX980's may overclock better thus closing the gap slightly.

So again, unless you observe micro-stutter (there's often stutter but it's not necessarily caused by SLI) I don't think it's worth it.
