How does it compare (score wise/FPS wise) to your "old" 980Ti's ?
It depends on how the games would scale with SLI.
Games such as Deus Ex Mankind Divided was poor at SLI scaling so there's a noticable jump in performance.
There's less stuttering too.
I've also bought a VR front panel for the PC since the GPU also has a front facing HDMI port. This way I can plug the Oculus into the front of my PC rather than round the back.. not just for convenience, but it also gains another foot or two in extra cable length for VR
