With Pascal Ahead, A 16-Way Recap From NVIDIA's 9800 GTX To Maxwell

In preparing to hopefully test the GeForce GTX 1070/1080 "Pascal" graphics cards under Linux in the days ahead, I've been re-testing my collection of available NVIDIA GeForce graphics cards going back to the GeForce 9800GTX up through the Maxwell-based GeForce GTX 980 Ti and GTX TITAN X. Besides looking at the OpenGL performance at 1080p and 4K, I've also been recording the power metrics and performance-per-Watt data.
