In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 Ti 3-way SLI are significantly better than the Nvidia GeForce GTX 780 DirectCU II Edition.
The GTX 660 Ti has a 52 MHz higher core clock speed and 144 more Texture Mapping Units than the GTX 780. This results in the GTX 660 Ti providing 141.7 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 660 Ti has a 52 MHz higher core clock speed and 24 more Render Output Units than the GTX 780. This results in the GTX 660 Ti providing 24.5 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 780 was released less than a year after the GTX 660 Ti, and so they are likely to have similar driver support for optimizing performance when running the latest games.
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 660 Ti has 3072 MB more video memory than the GTX 780, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 660 Ti also has superior memory performance overall.
The GTX 660 Ti has 144.2 GB/sec greater memory bandwidth than the GTX 780, which means that the memory performance of the GTX 660 Ti is massively better than the GTX 780.
The GeForce GTX 780 DirectCU II Edition has 2304 Shader Processing Units and the GeForce GTX 660 Ti 3-way SLI has 4032. However, the actual shader performance of the GTX 780 is 2078 and the actual shader performance of the GTX 660 Ti is 3951. The GTX 660 Ti having 1873 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 660 Ti delivers a massively smoother and more efficient experience when processing graphical data than the GTX 780.
The GeForce GTX 660 Ti 3-way SLI requires 450 Watts to run but there is no entry for the GTX 780. We would recommend a PSU with at least 600 Watts for the GTX 780.

Mini Review | GeForce GTX 780 DirectCU II Edition is a special edition of the high-end GeForce GTX 780. This edition comes with a custom dual fan cooling solution which should allow a slight performance boost, as GeForce GTX 780 benefits from the GPU Boost 2.0 technology. It does not have any overclocking out of the box. Benchmarks indicate a 1% performance boost when compared to the reference card. | GeForce GTX 660 Ti 3-way SLI is a solution of three GeForce GTX 660 Ti put together using NVIDIA'S SLI technology. Check the page of GeForce GTX 660 Ti to know more about its chip. As usual, SLI relies a lot on proper driver support and may suffer from micro-stuttering in lower frame rates (below 30). Benchmarks indicate the performance is overall, is up to X% better than a single GeForce GTX 660 Ti performing by itself but at times (depending whether or not the 3D game supports SLI or in the graphics driver) it performed worse than a single GeForce GTX 660 Ti. Expect this combination to draw up to 450 Watt though the average power consumption should be slightly lower. Even the most demanding games will run at the highest settings. |
