Performance in Simulators
There are large gaps between products from different classes in this racing sim. The best that our SLI tandem of GeForce GTX 550 Ti cards can do is overtake the GeForce GTX 560 Ti.
The game runs rather fast even on the single Zotac card, though. On the other hand, we can see that it certainly prefers a more advanced GPU architecture to a higher GPU clock rate.
Performance in Strategies
StarCraft II: Wings of Liberty
The struggle is quite fierce in this test: the GF116-based SLI tandem matches the GeForce GTX 570 at 1600x900 and wins at 1920x1080 but the GTX 570 then beats the SLI configuration at 2560x1600.
The Zotac card is 17% ahead of the reference sample, yet still cannot catch up with the GeForce GTX 560 Ti.
Total War: Shogun 2
Here is another recent addition to our list of tests. Unfortunately, the latest installment in the famous Total War series is not compatible with SLI technology. Hopefully, Nvidia will solve this problem with the next ForceWare release.
You have to lower your graphics quality settings or choose a faster graphics card than the Zotac GeForce GTX 550 Ti AMP! Edition in order to play Total War: Shogun 2 comfortably.
