Reasons to consider Radeon Vega 8

75 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 Direct3D 12 Async Compute.
Supports FreeSync.
Supports ReLive (allows game streaming/recording with minimum performance penalty).
Supports TrueAudio.

Reasons to consider GeForce GTX 660

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Based on an outdated architecture (Nvidia Kepler), there are less performance optimizations for current games and applications.

GeForce GTX 660

HWBench recommends GeForce GTX 660

Based on theoretical specifications.
