Yes, I took the lowest difference, I have to admit that.
GTX970 and GTX980 do differ only around 5-15% as long as the VRAM usage does not go beyond 3.5GB.
For 1440p or above, some games need already more than 3.5GB VRAM.
If the VRAM usage is over 3.5GB, GTX980 can go up to 30% faster than GTX970.
For 4k, both give up.
GTX970 is really sh*t if the VRAM usage go above 3.5GB.
GTX980 and GTX970 has around €150-200 difference, while GTX980Ti only €100-150 higher than GTX980, which makes GTX980 as a not so good buy.
GTX980 can go up to 30% faster than GTX970 on some cases but GTX980Ti is about 80-100% faster all the time.
GTX980 is no longer that overpriced but still can not join the bestbuys in my opinion.
GTX980Ti is an overkill for 1440p most of the times today but for games like Witcher 3, a single GTX980Ti is just right.
Totally Agree with everything now.
@flave , Let start from scratch:
a 980ti build with a 4k monitor is way out of budget:

Aus dollars and us dollars are quite different. I beleive , you should stick to a 970 build and full hd screen.
