I'm gonna be the advocate for the 980.
The extra .5 GB of video ram isn't something that makes a big difference now, but if anything in the future pushes your card to that spot, you'll need the 980.
6-10 fps in very graphically intensive games may not sound like a lot, but it's a significant difference. 70 fps is definitely a noticeable improvement over 60. A lot of the benchmarks that show only small fps gains for the 980 are running games at huge resolutions, where both the 970 and 980 struggle to break 30-40 fps. Very few modern games will push the 980 below 60fps at 1080p, and the performance difference between the 2 cards will be more significant at those fps levels.
I don't agree that you'll need to upgrade no matter what in a few years. The 980 should be more than you need for quite a few years. I mean, it's currently top of the pack, and even beats the titan for many apps. And the performance increases between generations of cards are inconsistent. The differences between the 5xx,6xx, and 7xx series of nvidia cards were relatively small. The 9xx series (Maxwell architecture) was a massive leap and amd still doesn't have a good answer to it. I think future generations will again be smaller performance increases until some revolutionary arch that puts Maxwell to shame comes out (not anytime soon).
The 980 also is currently the best option for running ut4 at1080p, 144fps, and probably will still be close to the best option in a few years.
If you want price/performance, the 970 wins. But if you want something more future proof that will give you the best or close to the best performance for the forseeable future and likely many years after, the 980 is worth the extra money.
PS. Any modern i5 or i7 won't bottleneck even tri-sli 980s in any modern game. There are tests showing 99% gpu utilization with 3 980s running different modern games on a system with an old 2.5 GHz i5
