You definitely should. There are at least 5 glaring issues with that "blind study".
1) The study was not performed on brand angostic users exclusively. In fact, only 4 people preferred AMD products to 19 people who preferred NV,
before any testing began.
2) 10 users knew what test systems used which parts which automatically means there was some flaw(s) in the methodologies as no one should ever be able to guess which PC has an AMD vs. NV GPU if the testing was truly blind.
3) It was chosen to test with VSync OFF, however, AMD's GPUs have lower input lag than NV's with Vsync ON. Now if I am playing a game that has wild FPS jumping from 40-80 fps, I am not about to go and turn VSync Off for my 35-60 fps range and then go turn back VSync on when my game exceeds 60 fps. That means I'll probably pick gaming with VSync ON at all times. But this decision gives GSync a major win automatically per Linus' testing. How would things turn out if the entire test was conducted with VSync ON?
4) The competence of the testers themselves. People actually picked the gaming experience with BF4 on High (NV cards) over BF4 on Ultra (AMD cards) but it doesn't take a genius to realize that Ultra settings would bring down performance on the AMD setup. So if someone wanted to measure the smoothest experience (not IQ), the High setting would automatically win.
5) Borderlands 2 was an automatic win for NV (see details in the test).
-----------------------
As far as some commenters mentioning that AMD makes cards that run hot and loud,
Sapphire Fury Tri-X is quieter at max load than NV's reference 980Ti is at idle. Fury cards are also cool.
After how many people bought the jet engine Gigabyte G1, GTX970/980/980Ti reference cards, it's become obvious that noise levels do NOT matter when it comes to NV products for NV fans when comparing NV vs. AMD videocards. Noise levels and low temps ONLY matter if it's good enough to justify one's purchase of an NV card for fans of that brand but as soon as NV starts losing in those metrics (or any metric), this metric no longer matters.
As a side-note, having worked in Asia and Middle East and of course having lived and visited Russia and Brazil, based on my anecdotal evidence, in 3rd world/developing countries, people are most brand attached (this isn't just about NV). In any event, in Central Asian country I've lived, the market share for NV sales based on discussions with store managers was close to 99%. They don't sell AMD cards at all unless the customer custom ordered it from Urumqi, China or Taiwan. In Russia and Brazil, the love for American brands is incredible, and they also automatically associate higher priced products = better. NV wins in those markets automatically.
The biggest problem I see this round is there is a huge wave of brand agnostic gamers who are leaving AMD. We already knew that at least 50% of the video game market was committed to NV. The second major factor is AMD's nearly complete loss of market share in the laptop market. Even if the laptop / desktop dGPU market was split 50%/50%, with NV having 90% of the laptop market and 60% of the desktop market (NV's historical trend), NV would already have 75% overall dGPU market share. However, we know that the notebook dGPU market is greater than 50% of the entire dGPU market which makes perfect sense how NV's overall market share is 80%+.
NV's CEO also sites that more gamers in China and other developing markets are moving to high-end graphics cards:
Nvidia: China is shifting to high-end GPUs
That would explain how NV's revenue and ASP keep rising while gross margins are in the 55-56% range quarter after quarter, a far cry from the much lower gross margins during Tesla, Fermi and early part of Kepler generations. I wouldn't be surprised if NV jacked up the price of 980's successor to $599 even if it only beats 980Ti by 20% (recall it was insulting and unheard of for a next-gen mid-range to go up from $249 to $499 with GTX680 but even a 680 was 35% faster than a 580). It'll be interesting to see how Maxwell fares in 1.5 years from now as far as driver optimizations go. Given that NV has UE4 under its belt and GW is firing on all cylinders as far as closed-source code optimizations go, NV is going to have full control over GPU obsolescence.
NV is mainly providing the Tegra chipsets but the software is likely made by 3rd parties. The Virtual Cockpit is powered by Google Maps while the MMI interface is Apple's Car Play and Android's OS version:

NV's CEO is a very smart/visionary CEO and that's why I love him for that as he foresaw that cars of the future will need powerful computers, deep learning and so on to become safer, more connected to the world and more efficient. This is yet another flop of ATI's management in the past where they sold early predecessors of Adreno (acrynom for Radeon) to Qualcomm. ATI could have been at the forefront of automotive SoCs but again no one at that firm has a correct vision to carry through.
JHH is very smart. He didn't just pick random auto firms either but the
fastest growing luxury makers who wouldn't blink at the cost of Tegra SoC. If NV continues to execute well, it shouldn't be too difficult for them to infiltrate the entire line-ups of AMD, Mercedes, VW and BMW vehicles over the next 10 years. That market could be huge, far more profitable than AMD being in consoles.
