I completely disagree with the above. Ignoring what you just said, I'd recommend going for 1440p instead of 4K because even the 1080Ti won't be enough for 4K high frame rates in a lot of titles.
But since you explicitly said you're not interested in any of that, I'd say that's a pretty sweet monitor right there. If you can afford it and it's what you want, there's no reason why you shouldn't go for it.
