Latest TitanV review comes from ComputerBase, with latest drivers, and an i9-7890X CPU, not the best CPU for gaming, but what the heck.
Avg performance over 25 titles @4K is 30% above 1080TI FE, with notable oddities such as Prey and Kingdom Come (CryEngine games) exhibiting 40% uplift over 1080Ti. Wolfenstien 2 exhibited almost no uplift whatsoever though.

'Turing mid-range GPU' (256-bit GDDR6 bus) still will beat it as far as I can predict good.
