Arguably, an Asus RoG motherboard would be the best.
Although even before 2019 the Z87 chipset will be quite old...
But you should have the financial recourses to upgrade well before then! Think positive!!
I do agree in you decision to get a good board. Another thought, besides the OC potential: most software that isn't free is licensed to your build. I don't have a lot of expensive software, but MS office, a few videos editing suites, ect... are worth ~$1000. So I went with an Asus pro board on my latest build.
