After now reading your newer article about the actual builds and benchmarks, I have to say some more things about your luxury system:
1. your case choice obviously was poor ( https://www.techspot.com/guides/1008-pc-buying-guide-benchmarks/page3.html ) ... you yourself say it's overkill, but in reality it's just waste of space. Today building a computer is mostly about how much power you can squeeze into tiniest box possible, so it can still breath and not overheat - and this 3 times more expensive and 2 times bigger case that necessary is really not the right choice.
2. after seeing your gaming performance tests I have to say your monitor choice (Dell UltraSharp U3014 30" $1120 @ 2560 x 1600) ... or GPU setup was also not optimal ... because the bottleneck is your GPU power right now vs your resolution. You should either:
a) put 2x 970 or 2x 980 in SLI
b) chose lower resolution monitor ... I myself would have picked one of those 34" 21:9 monitors @ 2560x1080 resolution ... for example BenQ XR3501 Curved LCD Gaming Monitor with 144MHz if it's on sale now.
c) both a+b so the monitors 144MHz wouldn't go waste
Yeah I am not going to argue with the case choice.
However I strongly disagree with your monitor comments. I cannot stand the 2560x1080 monitors, the aspect ratio is terrible for general usage and even gaming in my opinion.
I even prefer 16:10 over 16:9 and the quality of the Dell UltraSharp U3014 30" is amazing which is why professionals use them.
The BenQ XR3501 that you recommend is also a VA panel, gross. In comparison it would look shocking sitting next to the U3014.
I game on a U3014 with a single GTX 970 and most games are fine, I just dial down the settings that make no real visual difference and its very smooth.
