Reasons to consider GeForce GTX 580

Supports PhysX

Based on an outdated architecture (Nvidia Fermi), there are no performance optimizations for current games and applications

Reasons to consider Radeon HD 7950

44 watts lower power draw. This might be a strong point if your current power supply is not enough to handle the GeForce GTX 580 .

This is a much newer product, it might have better long term support.

Supports Direct3D 12 Async Compute

Supports ReLive (allows game streaming/recording with minimum performance penalty)

Supports Mantle

Based on an outdated architecture (AMD GCN), there may be no performance optimizations for current games and applications

No clear winner declared

These graphics cards seems to have comparable performance based on the game benchmark suite used (2 combinations of games and resolutions).
