    Summary

    Synthetic performance index

    • GeForce GTX 880M
      150%
    • GeForce GTX 960M
      100%

    Relative performance

    Reasons to consider GeForce GTX 880M

    Around 50% higher average synthetic performance.
    Supports PhysX
    Supports G-Sync
    Supports ShadowPlay (allows game streaming/recording with minimum performance penalty)
    Based on an outdated architecture (Nvidia Kepler), there are less performance optimizations for current games and applications

    Reasons to consider GeForce GTX 960M

    47 watts lower power draw. This might be a strong point if your current power supply is not enough to handle the GeForce GTX 880M .
    This is a much newer product, it might have better long term support.
    Supports PhysX
