In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 750 Gainward 2GB Edition are marginally better than the AMD Radeon R7 260X v2 PowerColor OC 1GB Edition.

The GTX 750 has a 55 MHz higher core clock speed than the R7 260X, but the R7 260X has 24 more Texture Mapping Units than the GTX 750. As a result, the R7 260X exhibits a 23 GTexel/s better Texture Fill Rate than the GTX 750. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 750 has a 55 MHz higher core clock speed than the R7 260X and the same number of Render Output Units. This results in the GTX 750 providing 0.9 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 750 was released less than a year after the R7 260X, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GTX 750 has 1024 MB more video memory than the R7 260X, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the R7 260X has superior memory performance.

The R7 260X has 14.4 GB/sec greater memory bandwidth than the GTX 750, which means that the memory performance of the R7 260X is slightly better than the GTX 750.

The GeForce GTX 750 Gainward 2GB Edition has 512 Shader Processing Units and the Radeon R7 260X v2 PowerColor OC 1GB Edition has 896. However, the actual shader performance of the GTX 750 is 804 and the actual shader performance of the R7 260X is 784. The GTX 750 having 20 better shader performance is not particularly notable, as altogether the R7 260X performs better when taking into account other relevant data.

The GeForce GTX 750 Gainward 2GB Edition requires 55 Watts to run and the Radeon R7 260X v2 PowerColor OC 1GB Edition requires 105 Watts. We would recommend a PSU with at least 400 Watts for the GTX 750 and a PSU with at least 500 Watts for the R7 260X. The R7 260X requires 50 Watts more than the GTX 750 to run. The difference is significant enough that the R7 260X may have a slight adverse affect on your yearly electricity bills in comparison to the GTX 750.
