Performance in First-Person 3D Shooters
Aliens vs. Predator
The SLI configuration built out of two GeForce GTX 560 Ti cards boasts a scalability of 80-90% in this test. It is 17% ahead of the Radeon HD 5970 at 2560x1600 but cannot make that resolution playable due to the low bottom speed which is a mere 2 fps higher than that of the GeForce GTX 580.

Well, it becomes clear that Nvidia’s next dual-chip graphics card won’t be based on GF114 chips because the SLI tandem isn’t much faster than the Radeon HD 5970. It won’t beat the upcoming Radeon HD 6990. In this test, the GeForce GTX 560 Ti SLI enjoys an advantage of 18% over the AMD flagship at 1920x1080 and less than 7% at the other resolutions.
Call of Duty: Black Ops
Multi-GPU configurations still depend too much on software optimizations. Here, the GeForce GTX 560 Ti SLI refuses to work at resolutions up to 1920x1080 but then offers a 43% performance boost over the single such card at 2560x1600. It didn’t overtake the Radeon HD 5970, though.
In our earlier tests a GeForce GTX 570 SLI tandem was unsuccessful in making this game playable with all possible comfort at the highest settings. Of course, the less advanced SLI configuration with two GeForce GTX 560 Ti cards cannot do that, either. It is even slower than the Radeon HD 5970 at 1600x900 and a mere 7% ahead of the latter at 1920x1080. That’s not enough to claim unrivalled superiority.
This game is tested with tessellation turned on.
The SLI configuration is ahead of the Radeon HD 5970 by 20% at 1600x900, by 15% at 1920x1080, and by a mere 5% at 2560x1600. That won’t be enough to compete with the upcoming Radeon HD 6990 considering the latter’s specifications. We guess Nvidia’s future flagship will carry two GF110 chips on board, probably in their full configuration with 512 stream processors active in each chip. The tested SLI tandem shows high scalability, though. It is about 70-75%. On the other hand, we can only recommend it for a two-step upgrade. If you want such performance right now, you should prefer the single GeForce GTX 580 which is free from the compatibility issues typical of multi-GPU configurations.

We turn tessellation on in this game.
This game suggests that a dual-GF114 card wouldn’t be a viable solution. The SLI configuration works well but is always inferior to the single GeForce GTX 580, the gap varying from 7 to 10% depending on the resolution. Considering the comparable cost of the two solutions and the problems typical of SLI configurations, we don’t see any reason to prefer the GeForce GTX 560 Ti pair.
