28-Way NVIDIA GeForce GPU Comparison On Ubuntu: From GeForce 8 To GeForce 1080
Metro Last Light Redux runs on Fermi GPUs and newer due to the OpenGL 4 requirements. Still a big spread in performance for those interested.
Team Fortress 2 becomes CPU bound with any relatively recent GPU at 1080p, but the performance-per-Watt is still a very interesting metric in this case.
