The Titan X, Titan Xp and in particular the Titan V are not targeted at domestic/consumer users. The Titan X and Titan Xp are enthusiast cards not commercial consumer products, and the Titan V is more specialised than either of those with a price to match.
The 1080Ti, Titan Xp and the Titan X use the same GPU with a few cores fused off and a higher base clock for the 1080Ti. If you are saying the 1080Ti is trash then you are saying the same of the Titan X and the Xp. I see little point to this thread though, if there is no question then I'd respectfully ask a moderator to close it.
