In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 970 EVGA Superclocked ACX 2.0 4GB Edition are marginally better than the Nvidia GeForce GTX 1060 3GB.

The GTX 1060 has a 341 MHz higher core clock speed than the GTX 970, but the GTX 970 has 32 more Texture Mapping Units than the GTX 1060. As a result, the GTX 970 exhibits a 12.8 GTexel/s better Texture Fill Rate than the GTX 1060. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 1060 has a 341 MHz higher core clock speed but 8 fewer Render Output Units than the GTX 970. The lower ROP count doesn't matter, though, as altogether the GTX 1060 manages to provide 7.1 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 1060 was released over a year more recently than the GTX 970, and so the GTX 1060 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 970.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The GTX 970 has 1024 MB more video memory than the GTX 1060, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 970 also has superior memory performance overall.

The GTX 970 has 32.2 GB/sec greater memory bandwidth than the GTX 1060, which means that the memory performance of the GTX 970 is noticeably better than the GTX 1060.

The GeForce GTX 1060 3GB has 1152 Shader Processing Units and the GeForce GTX 970 EVGA Superclocked ACX 2.0 4GB Edition has 1664. However, the actual shader performance of the GTX 1060 is 1969 and the actual shader performance of the GTX 970 is 2959. The GTX 970 having 990 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 970 delivers a noticeably smoother and more efficient experience when processing graphical data than the GTX 1060.

The GTX 1060 transistor size technology is 12 nm (nanometers) smaller than the GTX 970. This means that the GTX 1060 is expected to run slightly cooler and achieve higher clock frequencies than the GTX 970.

The GeForce GTX 1060 3GB requires 120 Watts to run and the GeForce GTX 970 EVGA Superclocked ACX 2.0 4GB Edition requires 150 Watts. We would recommend a PSU with at least 400 Watts for the GTX 1060 and a PSU with at least 500 Watts for the GTX 970. The GTX 970 requires 30 Watts more than the GTX 1060 to run. The difference is not significant enough for the GTX 970 to have a noticeably larger impact on your yearly electricity bills than the GTX 1060.
