If you consider the 1060 6 GB as a 100 points.
Then the 1050 Ti is around 60 points.
SO keep that in mind when comparing their prices and deciding what to get. Also it will depend on how much FPS you want at a specific resolution with your preferred settings in the games you play. Though if you're wondering 1080p@High Settings 50-60 FPS is the optimal experience. Not ULTRA settings.
