    Summary

    Reasons to consider GeForce GTX 770M

    Higher theoretical gaming performance, based on specifications.
    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    Based on an outdated architecture (Nvidia Kepler), there are less performance optimizations for current games and applications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 945M

    52 watts lower power draw. This might be a strong point if your current power supply is not enough to handle the GeForce GTX 770M .
    This is a much newer product, it might have better long term support.
    Supports PhysX
    Supports G-Sync
    Supports ShadowPlay (allows game streaming/recording with minimum performance penalty)
