Test Settings And Benchmarks

Do Two GeForce GTX 680s Beat Three GeForce GTX 660 Tis In SLI?

We tested Gigabyte’s GeForce GTX 660 Ti samples in both two- and three-way SLI, and its GeForce GTX 680 4 GB samples in single-card and two-way SLI configurations.

A reference-clocked GeForce GTX 680 2 GB helps us define the advantages of Gigabyte's overclocked boards with twice as much memory. Don't worry, the differences between clock rate and memory capacity will become perfectly clear as we work our way through the benchmarks.
