Help choosing a new mobo

[miseryguts]

I'll be (hopefully) embarking on my first build shortly but am having difficulty settling on a mobo & would appreciate some help choosing.
It will be used primarily for gaming/emulation & I'll be looking to overclock as far as I can safely go.

So far:

I'll be reusing the PSU, GPU, Air Cooler, Drives & Storage from my current rig at least for the time being as funds are limited.

The MSI Z97 has good quality.
