It was in the arstechnica review.
In the artechnica review the scores are pretty much identical across the board whether they use a 4 core without HT Haswell or a 6 core with HT Haswell so that suggests that even on a 980Ti and 290x, whether they are using DX12 or DX11, the game is GPU bound - unless it can't take advantage of more than 4 cores that is.
PC Perspective's results show little difference for Intel when going from 4 to 8 cores, although it does so by mixing CPU architectures.
It takes an i3 or an AMD chip to tank the throughput. Within AMD's CPU range, 6 to 8 cores is not a major performance change.
As far as GPU bound?
A= 980
B= 980 Ti
C= 290
D= 390
E = Fury X

There are two notable performance tiers for each IHV.
So, given the lovely way the tech press, the IHVs, and Oxide have handled a very immature platform:
A is on par to D
B is on par to E
C is on par to B
I don't have a direct comparison that can fully close the loop. There are frame numbers given that give rough equivalences, although that is risky given how noisy the set is.
However, even without the numbers, if we assume that the 290 <=390 and the 980 is <= the 980 Ti.
The 290 is bracketed as being less than or equal to the 390, yet on par with the the 980 Ti. That means there's no room for the < and everything is coming out the same. Either these chips are all the same or we have plenty of room for crap in these results.
It is not showing a clear sign we're getting what we should out of these GPUs or the preview methods.
But the crazy thing is, the 290x still gets a huge leap when using DX12 as opposed to DX11.
The most clear constant among the previews is that AMD's DX11 implementation is inferior.
To me, this looks like one of the least crazy things about how the performance testing has been handled across all these sites.
