Now we have the 2560x1600 crazy quality results and here the 970 and 390 produced similar performance despite the 970 being slightly slower. The 390 delivered 11% more performance and when looking at the mixed GPU results we received 16% more performance with the 390 as the primary card.
The 390X was still able to beat the 980, this time by a still convincing 16% margin.
The Fury X was 26% faster than the GTX 980 Ti at 1600p, which is obviously a massive performance advantage in favour of the Radeon graphics card. Interestingly the mixed GPU results only saw a 7% advantage when using the Fury X as the primary display driver. The Fury X/980 Ti combo was 51% faster than a single Fury X graphics card.
