Everyone loves to compare fury and fury x stock to reference cards stock because the perfomance is pretty even to a 980 or 980 ti but then they always conveniently leave out overclocking as if it doesn't matter. In the case you don't overclock...it's kind of a waste if you don't but then the cards are pretty even but who doesn't love more performance, especially at this level.
Strix 980 vs Strix Fury; Fury wins @1440p in guru3d reviews. Overclocking results are not guarranteed. You could end up with poor ASIC quality. Also I did not talk about reference cards at all; I showed STRIX vs STRIX results. At 1440p even the Strix 390X trades blows with the Strix 980.
