just sharing what hell I went through with a GTX 970 I bought. I experienced serious coil whine and changed to a R390 in the end and never looked back!!!
I've done some small research myself and would like to share about it too.
From at least 5 website reviews using the AMD LATEST DRIVERS, the R9 390 BEATS the GTX 970 in terms of raw power. Shadow of Mordor (and probably more upcoming heavyweight titles) also uses more than 3.5GB of RAM and causes micro stuttering in Nvidia's controversial 3.5GB +0.5GB RAM, and that's where the power of AMD R390's 8GB RAM comes in.
- for the Sapphire Nitro R9 390 8GB card, users will find that it is competitive with the performance of the GeForce GTX 970 4GB for a nearly identical price. It's not new, it's not flashy and it's not rewriting the world of GPUs, but it is at least slightly more than expected.

- Verdict : Sapphire’s Radeon R9 390 Nitro offers a tremendous value for the money. It operates very quietly and has performance that outpaces the competition. The Tri-X cooler keeps the GPU at a reasonable temperature and having 8GB of memory means you’ll have room for the high resolution textures sure to be found in future games.

Also google "GTX 970 coil whine." Plenty of pissed off owners of GTX 970 as well. A lot of owners are encountering coil whine issues (some seems badly mentally affected with the high pitched whines during benchmark loading, running etc ) with GTX 970 that are virtually close to none in AMD R390s. EVGA, MSI, ASUS, Gigabyte, Palit, Galaxy all have GTX 970 boards that may give you a potential coil whine nightmare especially for those who leave their side panels open and/or game without headsets. Some have did RMAs 4 times.
I bought a brand GTX 970 and got so pissed off with 2 exchanges of GTX 970 (Both still have coil whine, the last one is especially bad when paired up with a Corsair HXi-850 (Platinum). In the end, I went the AMD R390 route and never looked back. A quick test on 1600x900 unigine valley netted me 88 fps for the R390 over 78.9 fps for the GTX 970. That's a 9.1 fps advantage. A test on Uniheaven 1600x900 netted me 77.0 fps for the R390 over 72.8 fps for the GTX 970. That's a 4.2 fps, not too shabby. I'm running an Intel I7-6700K on an Asus Z170M-plus setup. Win 7 OS. 480 GB Sandisk Extreme Pro. Cooler Master V1000 (Gold). (Many corsair sucks, saw 2 units in RMA at the service centre, one is RM series another is HX series). My Cooler Master Silent Pro 1000 lasted me 6 years and still going strong.
No coil whine nightmare on R390. For the GTX 970, its a lottery draw for you. 50-50 it seems. If you're lucky, u get a good batch. If you're not lucky, you get your life turned upside down by coil whine. Sapphire Nitro R390 runs silent and kool. I would take higher power consumption + raw brute power over the hellish coil whine anyday. Note that I change cards between green and red camps regularly.
I went green, but went red again.
I'm not sure which camp I will be in in 5 years time though.
