Skyrim – SLI
The Elder Scrolls V: Skyrim (DirectX 9)
The Empire of Tamriel is on the edge. The High King of Skyrim has been murdered.
Alliances form as claims to the throne are made. In the midst of this conflict, a far more dangerous, ancient evil is awakened. Dragons, long lost to the passages of the Elder Scrolls, have returned to Tamriel.
The future of Skyrim, even the Empire itself, hangs in the balance as they wait for the prophesized Dragonborn to come; a hero born with the power of The Voice, and the only one who can stand amongst the dragons.
Our settings for Skyrim
Here is a video our testing run through, for your reference
As expected, SLI scaling is pretty minimal at 1080p with Skyrim though there is SOME benefit to adding a second card. In reality though, it isn't need for this game at these settings.
There is a little more benefit to multi-GPU here at 2560×1440 but still not enough to warrant the extra investment in my opinion. The GTX 780s in SLI though are MUCH faster than the Radeon HD 7970s in CrossFire – just about double!
Here we see a single GTX 780 performing about the same level as the GTX 680s in SLI; the GTX 780s in SLI see another 44% performance boost, without adding much frame time variance to the story.
