I have the ASUS Strix R9 Fury. It was an expensive version of the Fury, but I wanted the Strix DC3 cooler (for aesthetic reasons), but the 980ti Strix was way too expensive. Also, I wasn't prepared to pay the exorbitant upcharge for G-sync when most of the then G-sync monitors offered terrible quality control.
The GPU has been very good for my usage. I'm playing older games like GTA V, Dishonored, Bioshock Infinite, MGS V, Borderlands 2, Arkham Origins, Shadow of Mordor, etc. and the Fury is a beast for 1440p in those games. I'm pretty much able to max all of them out (GTA V being an exception as it's extremely demanding at max settings) and get 60 FPS or more. With some tweaking I could maintain 90 FPS in GTA V, which is the sweet spot for a competitive fast-paced game like that.
I bought it in September of 2015 for around £380, which at the time was a lot more in EURO (my currency) than what it is now. If Britain had left the EU sooner (that does not mean I support Brexit) then I would have paid about €470 versus €550. Ahh well. I also bought what I considered to be the best Freesync monitor at the time, the BenQ XL2730Z a 1440p/144Hz monitor. I've had a great time with this setup. It's a very nice monitor and the card runs at 70°C under load with the fans only being slightly louder than my previous Gigabyte G1 Gaming 970, which was very quiet and cool as well.
However, the GPU is lagging when it comes to modern games. The 4GB VRAM limitation and the disappointment that is DX12 has made the Fury a poor choice for buyers today. If you can find a Sapphire Nitro for £250 brand-new, that's a pretty good deal, but I wouldn't pay more than £300. And don't bother with the ASUS Strix version. While my overclocking was absolutely abysmal (I couldn't get 1050Mhz stable with extra voltage, the reference speed of the Fury X), reviews on Newegg for the card are consistently low, stating coil whine susceptibility (mine coil whines) and crashes. Gigabyte released a Fury with their Windforce cooler, but it went completely by the wayside as it was such a disastrous launch for AMD. The entire Fury line has sold only a handful when compared to previous AMD flagships and of course nVidia's flagships.
I'll be replacing the Fury with a Vega GPU in six months time or so and that means I'll be ready for any game that has come out in the last year. I don't mind this as I refuse to pay €60 for a half-finished game which most are these days. The last game I paid full price for was GTA V and it ran like crap on my GTX 970. To be more specific and fair, it ran really well but constantly crashed. It wasn't until I replaced the GPU with the Fury that it stopped crashing. That's not necessarily the games fault, but it was a common problem thousands of GTA V users were experiencing. I won't be paying full price for a game again.
If you're interested in a Fury, here is my recommendation:
Don't buy one if you...
...play the most recent games and want something that will last a long time (4GB is just not enough)
...can't find one for less than £300 (a 980ti can be found for £350, which with some overclocks is a far more powerful GPU)
...like overclocking (the Fury range was terrible for overclocking in general)
...play at 1080p (it's really better suited for older games at 1440p and a few DX12 games like Hitman)
Do buy one if you...
...play older games at 1440p
...play the few DX12 games that support it well (tell me which ones if you want to be sure)
...can find one for £250
