    • GeForce GTX 660
      216%
    • GeForce GTX 745 OEM
      100%

    Relative performance

    Reasons to consider GeForce GTX 660

    Around 116% 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    Based on an outdated architecture (Nvidia Kepler), there are less performance optimizations for current games and applications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 745 OEM

    85 watts lower power draw. This might be a strong point if your current power supply is not enough to handle the GeForce GTX 660 .
    This is a much newer product, it might have better long term support.
    Supports PhysX
    Supports G-Sync
