NVIDIA GeForce GTX 1060 Offers Great Performance On Linux
The GTX 1060 can indeed deliver the performance level of a GeForce GTX 980... Certainly the GTX 1060 is a big upgrade over the GTX 960...
The GTX 1060 does also beat out the Radeon RX 480 when it comes to OpenGL performance under Linux.
The GTX 1060 usually beats out the Radeon R9 Fury too under Linux. The AMD cards were tested with Linux 4.7 and Mesa 12.1-dev compared to the NVIDIA proprietary driver.
