That's way way too expensive considering the great used Tri-X 290 linked for $179 or the $220 one on Newegg had (EDIT: looks like that deal is gone as the best deals sell out fast). For $100-110 going with a 970/390, you get 2-5% more performance for 50%+ price premium. That's the very definition of wasting $. 8GB of VRAM is also a marketing gimmick against 290's 4GB.
Computerbase's
latest benchmarks confirm:
R9 290 OC (after-market 290) = 100%
R9 390 = 102%
GTX970 OC (after-market 970) = 104%
They also did separate testing which again confirmed that an
after-market 290 ~ reference 290X.
Incredible value at $180-220.
Then in 1.5-2 years, just sell that $180-220 290 for $100 and take the $100-150 saved from
not buying a 970/390 and just invest into a future 16nm GPU that will be 50-75% faster than a 970/290 at the $350 level by Fall 2017. This strategy has never failed in the last 3 decades of GPU upgrading. What has failed is people paying $150-300 more for 15-20% more performance thinking they are more future-proof. Not going to happen.
The reason 390 scores better than a 290 is because in most reviews the 290 used is a reference card that throttles or they are using older AMD drivers for the 290 scores vs. newer drivers for the 390 because they are too lazy to retest older cards on newer drivers. Also, there is a small increase in performance from faster GDDR5. Clock for clock 290 and 390 are more or less identical.
All it takes is a
1030mhz clock on the 290 to match a reference 290X.
R9 290 for $250 or less or EVGA B-stock 970 for $255 or so make every card in the $160-250 range irrelevant. The performance increase in those cards over 950/960/960 4GB/285/280X is massive.

TechPowerUp, despite slight preference for NV cards, had this to say in their recent $800 Build Guide:
"At just $249, the Radeon R9 290 TurboDuo offers current-gen tech. Our tests show that the R9 290 is a whopping 52 percent faster than the $50 cheaper GeForce GTX 960 at 1920 x 1080 pixels, our target resolution. It also offers 4 GB of video memory. PowerColor added a factory overclock on top of that. If this doesn't highlight NVIDIA's terrible pricing for the GTX 960, nothing will."
For someone who is interested in picking up MGS V, Asus Strix 970 is going for
$289 right now. Pretty good deal.
