GTX 1080 and 980 Ti in SLI?

[Subayyal]

I have a 980 Ti SLI config right now. I was wondering if I can sell one of the 980Ti and get a GTX 1080 to run with the remaining 980Ti in SLI?

Is it possible?

No.

Unless its changed over the past few months, no. You cannot SLI two different GPUs.

There has been talk about it in DX12, but even if it works, there arnt enough DX12 games out there to make it viable.

Stick with your 980ti SLI, the 1080 is only 20% faster than a single one anyway.

You CAN use them together but not in SLI. You can run a 1080 as your primary graphics card and use the 980ti as a physX card. However, that is not worth it and your performance may even go down (depending how good the 1080 actually is).

If you absolutely want to go 1080 then I recommend you sell your 980ti's.

In the same boat, running two 980Ti's. From what I understand, the SLI is going to give you on average better performance, though you have to deal with the lovely side effects of SLI, such as poor scaling. I'm personally waiting for the 1080 Ti, and I'm throwing two of those in there. I usually run my cards on a two year cycle, that way the value hasn't dropped so much that I'm really having to buy two cards, usually the SLI setup buys one of them and then I have to go out of pocket for the second one. I'm hoping that eventually a single card setup for Ultra Settings / 4K in 60 frames will exist, and then I'll move to a single card setup, but alas, it does not.

This made me laugh, a single 980 Ti for PhysX is hilarious. I know you're not recommending it, but even breathing that thought into life is a bit absurd lol. That's like buying a Ferrari to drive strictly through school zones.
