GPUs eventually came to a point where they were more than sufficient for the displays most people used them for (assuming most folks use 1080p monitors), but now displays are catching up, creating a return for the need of multi-GPU configurations. Of course, you still want those multi-GPU configurations to look good behind your case window, so you don't want to use any old SLI ribbon. If using AMD cards isn't an option, and you must absolutely not use SLI ribbons, you can always get an SLI bridge, which looks better.
There are a handful of vendors that make these SLI bridges, including Evga. Now, however, the company is introducing a new set of SLI bridges with the Evga Pro SLI Bridges V2.
The bridges have an aluminum shroud, and they feature built-in LEDs for some extra pizzazz. This LED will not work on all graphics cards, though -- only on Evga's GTX Titan, GTX 980, GTX 960, and GTX 780 and 780 Ti cards. It will also work on some of Evga's GTX 970s and GTX 770s. (Mind you, it's possible that they'll work on cards from other vendors, too, but we don't see why you would use an Evga bridge on a setup sporting, say, Asus or MSI cards.)
Evga also boasted that the bridges have a "high pixel clock design optimized for 4K+ and 120 Hz+ gaming," although we don't reckon that premium SLI bridges will do anything to improve performance over the cheap ribbons that come included with your motherboard.
The bridges will be available in two 2-way variants, along with a 3-way and 4-way variant. Evga hasn't listed any prices yet, nor do we know anything about availability beyond "soon." Considering the price of the original Nvidia bridges, we don't think these will cost mere pennies.
