It's been a long time since we've tested NVIDIA SLI and been able to see how the technology is going. To be honest, it hasn't really changed much since we last looked at the technology previously. That's not a bad thing, though, because SLI has always been very strong and when it comes to offering a good boost in performance, it's done an excellent job.
SLI and CrossFire ultimately are both very good these days, especially when it comes to just using two cards. Moving past that, the gains aren't always as impressive; of course they still exist, but the value isn't as strong when compared to moving from a single GPU setup to a dual GPU setup.
Going to an SLI setup, though, usually always just comes down to price. A single GTX 650 TI Boost is going set you back $169.99 meaning two comes in at $339.98. Against the AMD line up it's fair to say that performance of an SLI setup is similar to that of a single Radeon HD 7970 GHz Edition, which costs around $440.
With a $100 price difference you can see the value in going for this kind of SLI setup over the single higher end AMD option. Combined with the fact that SLI performance gains are strong and consistent, you'd find yourself hard pressed to justify the extra $100 for the AMD option.
Multi card setups aren't for everyone, but if you're looking for some good performance at a strong price point, with the way AMD and NVIDIA are being so aggressive with these mid-range video cards these days, it's something that you should really start to look at.
In the end we all want strong performance at a strong price point. For that reason this is a setup that you should really consider. What we really want to see, though, is the performance of some cards with aftermarket cooling. We'd like to get the temperature and noise levels a little lower. That's of course something we're going to be looking at over the coming days - stay tuned for more.
