When running @ 1440p with Ultra graphics settings, on average enabling SLI results in an additional 19 frames-per-second (an increase of 24.7%). Worth it? Even with a 144 Hz G-Sync monitor, probably not.
| Single GPU | SLI | |
| GPU 0 Temperature | 82° C | 80° C |
| GPU 1 Temperature | 37° C | 67° C |
| Average Frame Rate | 77 FPS | 96 FPS |
Here’s the fancy output from the game’s built-in benchmark with SLI enabled.
