Benchmark Reviews: Only a few years ago NVIDIA's SLI technology was a feature only the most elite gamers took advantage of, helping them to push the fastest graphics cards on the planet even faster. Often times a second GeForce video card could be combined into a SLI set and produce 33-50% more performance. Those days are gone, and Benchmark Reviews has learned that a set of GF106 GPUs can do a lot more than scale; they can multiply. Since a single $129 GeForce GTS 450 can outperform an AMD Radeon HD 5750 and match the 5770, what kind of performance do you get from two GTS 450's for $258? It seems like a pair of mainstream GTS 450's in SLI should compete nicely against AMD's $200 Radeon HD 5830, or maybe even their $270 Radeon HD 5850. As it turns out, two GTS 460's in SLI are good enough to threaten NVIDIA's top-end segment. In this article, Benchmark Reviews tests NVIDIA GeForce GTS 450 SLI performance scaling.
