Just Cause 2

The three premium-class graphics solutions are comparable in Just Cause 2, yet the GeForce GTX 680s are just a little bit faster than the dual-chip GTX 690 and the Radeon HD 7970 CrossFireX.
Aliens vs. Predator (2010)

SLI can boast record-breaking efficiency in Aliens vs. Predator (2010), close to 100%, yet the GeForce GTX 680 SLI cannot beat the Radeon HD 7970 CrossFireX anyway.
Lost Planet 2

These results are similar to what we've just seen in Aliens vs. Predator (2010) except for the highest-quality settings.
StarCraft II: Wings of Liberty
We have no surprises in this game:

The efficiency of SLI can only be evaluated at the highest-quality settings.
Sid Meier’s Civilization V

Nvidia’s multi-GPU technology works smoothly in Sid Meier's Civilization V, too. The SLI tandem is up to 90% faster than the single card. The Radeon HD 7970s are even faster, though.
Tom Clancy’s H.A.W.X. 2

The CrossFireX configuration is superior in Tom Clancy’s H.A.W.X. as well, but the GeForce GTX 680 SLI is very fast, too.
