GeForce GTX 560 Ti SLI Game Requirement Analysis
GeForce GTX 560 Ti SLI is a solution of two GeForce GTX 560 Ti put together using NVIDIA'S SLI technology.
SLI relies a lot on proper driver support and may cause micro stuttering in FPS below 30. This means this combination might even perform worse than a single GTX 560 Ti.
The optimal performance it delivers is better than single GeForce GTX 580 but relatively far from GeForce GTX 590.
Therefore, this combination is sufficient for gaming at 1080p and most demanding games can be played at the highest settings.
