GTX 780 SLI vs. single GTX 980Ti

[magellan]

Would two GTX 780's in SLI match up w/a single GTX 980Ti in terms of performance?

Id guess it would match or beat it. Not sure, but you can find an sli review and see.

That said, I wouldn't do it (sli). Power use, noise, potential hassle...versus one card is just not worth it. Sell your 780 and grab a 980ti.

Barely beats it. To the point where it isn't worth the extra power/noise/etc

+1 Go single card a lot of games don't support SLI and you don't double your performance with SLI some games show vary little improvement.

The Metro:LL benchmarks looked really bad in 780 SLI, I think those black lines indicate a lot of significant framerate variation.

How well do SLI and Crossfire work on Windows 10 relative to Windows 7?

The same really.

I know I probably shouldn't shoehorn this question into this thread, but isn't one of the big attractions of DX12 that you can use any two video cards in parallel to process graphics data? So that you can basically crossfire/SLI any two video cards? Or can you only crossfire DX12 compliant video cards?
The author of the article ED quoted stated that new console-centric games are working so badly w/SLI he wouldn't even consider an SLI rig.

Were did you find that information about DX12? From what I have read about DX12 it manly helps with CPU efficiency so you can use a older CPU to power a new game.

I just finished reading the article about the new DX12 there was no mention of SLI or Crossfire only CPU enhancements, reduced overhead, better threading, and ultimately a vastly more efficient means of submitting draw calls.

I initially read about the explicit multiadapter feature of DX12 in a very long DX12 thread here on overclockers. Here's another article discussing it:

The article even mentions an "Unreal Engine 4 Elemental Demo with an integrated GPU drawing some of the post-processing effects while the primary GPU worked on the next frame."
