Although a stock 980 Ti is inferior to a Titan X, I'd say that a non-reference or aftermarket 980 Ti, especially with a factory OC, is superior to the Titan X. Same more or less for the Radeon Fury X: although the Fury X has shown itself capable of beating a reference 980 Ti, a non-reference 980 Ti like an EVGA FTW, Asus Strix, or Gigabyte Windforce will cream any and all Fury X cards - only reference Fury X cards exist today, even if they are being sold by AIB partners such as Sapphire. And that's not even looking at "magnum opus" cards such as EVGA's Kingpin, Gigabyte's G1 Gaming, MSI's Lightning and Asus' Matrix.
