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 670 DirectCU II OC Edition.

The GTX 670 has a 65 MHz higher core clock speed than the GTX 660 Ti, but the GTX 660 Ti has 224 more Texture Mapping Units than the GTX 670. As a result, the GTX 660 Ti exhibits a 197.6 GTexel/s better Texture Fill Rate than the GTX 670. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 670 has a 65 MHz higher core clock speed than the GTX 660 Ti, but the GTX 660 Ti has 40 more Render Output Units than the GTX 670. As a result, the GTX 660 Ti exhibits a 34.5 GPixel/s better Pixel Fill Rate than the GTX 670. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 660 Ti was released less than a year after the GTX 670, 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 4096 MB more video memory than the GTX 670, 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 240.3 GB/sec greater memory bandwidth than the GTX 670, which means that the memory performance of the GTX 660 Ti is massively better than the GTX 670.

The GeForce GTX 670 DirectCU II OC Edition has 1344 Shader Processing Units and the GeForce GTX 660 Ti 3-way SLI has 4032. However, the actual shader performance of the GTX 670 is 1422 and the actual shader performance of the GTX 660 Ti is 3951. The GTX 660 Ti having 2529 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 670.

The GeForce GTX 660 Ti 3-way SLI requires 450 Watts to run but there is no entry for the GTX 670.

GPU Mini Review

Mini ReviewGeForce GTX 670 DirectCU II OC Edition is a Special Edition of the powerful GeForce GTX 670. See the standard version for more information about it.
The new features include an increase in the core-clock that went from 915MHz to 980MHz while the Turbo Boost is now of 1058MHz. A 20% more effective cooler is also included.
The performance boost is significant and around 5% when compared to the standard GTX 670.
Most demanding games will run at the highest settings.
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.
