OMG! Do you not even understand a single word that you wrote here? There have been manufacturers trying to come out with such an adapter for over a year now, and yet, we still have none on the market. Not a single manufacturer has released a product, not a single one has confirmed of a release date in sight. The best thing we have is a vague, might be Q4 2015, which might be Q1 2016, which might be even later, or never because by then there will already be a whole new generation of devices out, people who would have wanted this adapter will have given up and purchased other hardware that supports what they actually want to do, etc. We have no idea of the price of said mythical, non-existent adapter. It is speculated to be in the $100 range, but could just as easily be $150 or even $200.
And without such an adapter to connect the Fury X to the TV, you WON'T get higher FPS than a 980 TI, because your Fury X will never be able to display more than 30 FPS no matter how fast it might be able to calculate and draw them in the card because the TV won't accept more than 30, but the 980 TI using HDMI 2.0 will be able to push up to 60 FPS on the games that it can do so on... And going back a few pages, there are not many games that a 30 FPS limit would not greatly, negatively impact the performance of the Fury X at 4k compared to what a 980 TI would be able to do on the same TV all because it has HDMI 2.0 and can push up to 60 FPS refresh.
As has been said by many people, this is a HUGE oversight, and a massive blunder. The couple extra $ saved on the connector and minor design changes on the hardware itself to support the proper interconnect was a very poor trade-off given the current state of 4K displays.
So lets see what not having HDMI 2.0 actually means to all the people who have a modern 4K TV which doesn't have display port but only HDMI 2.0:
