In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 Ti 3-way SLI are very slightly better than the AMD Radeon R9 280X Crossfire.

The GTX 660 Ti has a 65 MHz higher core clock speed and 80 more Texture Mapping Units than the R9 280X. This results in the GTX 660 Ti providing 89.8 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 65 MHz higher core clock speed and 8 more Render Output Units than the R9 280X. This results in the GTX 660 Ti providing 11.5 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 R9 280X was released over a year more recently than the GTX 660 Ti, and so the R9 280X is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 660 Ti.

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 Radeon R9 280X Crossfire and the GeForce GTX 660 Ti 3-way SLI have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The R9 280X has 143.4 GB/sec greater memory bandwidth than the GTX 660 Ti, which means that the memory performance of the R9 280X is massively better than the GTX 660 Ti.

The Radeon R9 280X Crossfire has 4096 Shader Processing Units and the GeForce GTX 660 Ti 3-way SLI has 4032. However, the actual shader performance of the GTX 660 Ti is 3951. The R9 280X having 145 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 280X delivers a noticeably smoother and more efficient experience when processing graphical data than the GTX 660 Ti.

The Radeon R9 280X Crossfire requires 550 Watts to run and the GeForce GTX 660 Ti 3-way SLI requires 450 Watts. We would recommend a PSU with at least 1000 Watts for the R9 280X. The R9 280X requires 100 Watts more than the GTX 660 Ti to run. The difference is significant enough that the R9 280X may have an adverse affect on your yearly electricity bills in comparison to the GTX 660 Ti.

GPU Mini Review

Mini ReviewRadeon R9 280X Crossfire is a solution of two Radeon R9 280X put together using AMD'S Crossfire technology.
Check the page of Radeon R9 280X to know more about its chip.
Crossfire 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 60% better than a single Radeon R9 280X performing by itself but at times (depending whether or not the 3D game supports crossfire or in the graphics driver) it performed worse than a single Radeon R9 280X. Expect this combination to draw up to 550 Watt though the average power consumption should be slightly lower.
Even the 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.
