NVIDIA GeForce GTX 1080 SLI @ techPowerUp
 

Crysis 4K at more than 60 FPS! We take a close look at multi-GPU SLI with two GeForce GTX 1080 cards in 16 games and 4 resolutions. We used an SLI HB bridge for all testing, but also have numbers with the old bridge to find out whether a high-bandwidth bridge is absolutely necessary for SLI on Pascal.
