We were very impressed with NVIDIA's GeForce GTX 660 Ti, an upper mid-range graphics card priced at US$299, utilizing the same GK104 core found in NVIDIA's GTX 670 and flagship GTX 680 cards. In our performance tests the GTX 660 Ti performed much better than its competitor from AMD, the Radeon HD 7870, and even beat AMD's upper-tier HD 7950 on the majority of tests. In NVIDIA's lineup, the GTX 660 Ti's overall performance put it just behind NVIDIA's GeForce GTX 670.
Thanks to its reasonable price point compared to high-end cards, we reckon many enthusiasts would be considering the basic GTX 660 Ti for a two-way SLI configuration. To fulfill that desire, today we're going to find out just how well a pair GTX 660 Ti cards can perform.
To evaluate the GeForce GTX 660 Ti’s performance in a 2-way SLI configuration, we will be using our same Intel X58 setup which has the following specifications:
As no reference design is available for the GTX 660 Ti (at the point of our test), we'll be using custom cards downclocked to reference specs, which should give you an idea of the bare minimum performance you can expect out of a GTX 660 Ti 2-way SLI configuration.
We did not include NVIDIA's GeForce GTX 680 as its single card performance is quite close to the GTX 670, while its SLI performance is very close to the GTX 690.
