1. First off, I wouldn't put much stock on youtube videos unless they are associated with a well respected test site. The usual mindset is to pick a position, and then handpick games or apps that support the predetermined conclusion. My fav one of these is the guy that used "opening 100 Chrome tabs" to **prove** how big an impact SSDs have. As if that was something that any PC user does each day.
2. DX12 represents an extremely small % of present games at this point ... there's 3 in Techpowerup's 17 game test suite and it one of those they used DX11 implementation as DX12 was bonkie.... yeah, it's a technical term
3. The teams responsible for DX12 APIs focus will be in looking good in today's major games. DX12 is a new API and you should expect that driver teams will still be tweaking DX12 by the time January 2018 rolls around.
4. The metrics used by the GPU.boss website do not coincide well with the typically used gamer resources.
5. The drawbacks to be considered on the Fury are:
a) Most available are reference designs
b) Extremely limited overclock headroom, with both overclocked, the Fury is substantially behind the others
c) Heat
d) Power (25 - 100 watts)
e) Noise (about 10 db)
f) Increased PSU and case fan requirements
6. Every GPU decision will however be an individual one, it depends on the games you will play.... if the only game you play performs better on a certain card, then that's the card you should get. If you play a wide spectrum of games, then you should review test sites that test a wide range of games. TPU for example usually has about 17 of the day's most popular games in their test suite.
However, with AMDs next generation about to drop ... I would wait till we see how they perform .... then wait 3 more weeks for the AIB versions to arrive. Even if you don't bite, it will have an immediate effect on the pricing of the other cards you are considering. Card pricing is essentially determined by the consumer .... manufacturer's initially price their cards base upon what they perceive consumers will find attractive based upon relative worth. If they guess wrong, prices are adjusted accordingly.
