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 590 Mars II Asus Edition.

The GTX 660 Ti has a 133 MHz higher core clock speed and 208 more Texture Mapping Units than the GTX 590. This results in the GTX 660 Ti providing 207.3 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 133 MHz higher core clock speed than the GTX 590, but the GTX 590 has 24 more Render Output Units than the GTX 660 Ti. As a result, the GTX 590 exhibits a 9.2 GPixel/s better Pixel Fill Rate than the GTX 660 Ti. 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 over a year more recently than the GTX 590, and so the GTX 660 Ti is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 590.

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 590, 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 47.8 GB/sec greater memory bandwidth than the GTX 590, which means that the memory performance of the GTX 660 Ti is noticeably better than the GTX 590.

The GeForce GTX 660 Ti 3-way SLI has 4032 Shader Processing Units and the GeForce GTX 590 Mars II Asus Edition has 512. However, the actual shader performance of the GTX 660 Ti is 3951 and the actual shader performance of the GTX 590 is 801. The GTX 660 Ti having 3150 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 590.

The GTX 660 Ti transistor size technology is 12 nm (nanometers) smaller than the GTX 590. This means that the GTX 660 Ti is expected to run slightly cooler and achieve higher clock frequencies than the GTX 590.

The GeForce GTX 660 Ti 3-way SLI requires 450 Watts to run and the GeForce GTX 590 Mars II Asus Edition requires 499 Watts. We would recommend a PSU with at least 700 Watts for the GTX 590, but we do not have a recommended PSU wattage for the GTX 660 Ti. The GTX 590 requires 49 Watts more than the GTX 660 Ti to run. The difference is significant enough that the GTX 590 may have a slight adverse affect on your yearly electricity bills in comparison to the GTX 660 Ti.

GPU Mini Review

Mini ReviewGeForce 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.
GeForce GTX 590 Mars II Asus Edition is, just like GeForce GTX 590, a combination of two GeForce GTX 580 but with increased clock frequencies.
Just like GeForce GTX 590, GeForce GTX 590 Mars II Asus Edition 3GB of video memory but Asus managed to increase the core-clock from 607MHz to 782MHz and the memory clock from 885MHz to 1002MHz. This huge over clock drastically increases the heat produced so "Twin oversized 120mm fans" were also included.
Benchmarks indicate the performance is about 15% better than the standard GeForce GTX 590.
Even the most demanding games will run at the highest settings.
