In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 560 Ti Gigabyte OC 1GB Edition are massively better than the AMD FirePro V3900.

The GTX 560 Ti has a 250 MHz higher core clock speed and 40 more Texture Mapping Units than the FirePro V3900. This results in the GTX 560 Ti providing 42 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 560 Ti has a 250 MHz higher core clock speed and 24 more Render Output Units than the FirePro V3900. This results in the GTX 560 Ti providing 23.6 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 FirePro V3900 was released over a year more recently than the GTX 560 Ti, and so the FirePro V3900 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 560 Ti.

The FirePro V3900 and the GeForce GTX 560 Ti Gigabyte OC 1GB Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GTX 560 Ti has 99.2 GB/sec greater memory bandwidth than the FirePro V3900, which means that the memory performance of the GTX 560 Ti is massively better than the FirePro V3900.

The FirePro V3900 has 480 Shader Processing Units and the GeForce GTX 560 Ti Gigabyte OC 1GB Edition has 384. However, the actual shader performance of the FirePro V3900 is 203 and the actual shader performance of the GTX 560 Ti is 691. The GTX 560 Ti having 488 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 560 Ti delivers a massively smoother and more efficient experience when processing graphical data than the FirePro V3900.

The FirePro V3900 requires 75 Watts to run but there is no entry for the GeForce GTX 560 Ti Gigabyte OC 1GB Edition. We would recommend a PSU with at least 350 Watts for the FirePro V3900.
