Not really much to say. My card is at hard work in my rig. Playing games in 4k almost max settings on every game @60fps. I slapped a Heatkiller block on it (along with a backplate) and it's much better than stock. Haven't overclocked it though, haven't been bothered to.
EDIT: Might also add that I thought nVidia was screwing us original titan x (pascal) owners over with the new release of the card. I probably won't upgrade to the next gen since I can't upgrade my 4k60hz monitor (yet).
