New build, help me decide on mobo!

[savagemessiah115]

I'm building my second pc... since my first build didn't go as well as I planned I wanted to do this right!
I've decided so far!
Case: Deppcool - mini-ITX Tristellar
CPU: Ryzen 7 2700x
Cooler: Corsair - H60 54.0 CFM Liquid CPU Cooler
RAM:G.Skill 
F4-3200C16D-16GVKB
PSU:CM-Masterwatt TUF 750w
GPU: TitanXp

I can't decide this!

ASRock AB350M Pro4
Form Factor: Micro ITX | Socket: AMD AM4 | Chipset: AMD Promontory B350 | Memory Support: Dual-Channel 4 x DDR4 3,200MHz (up to 64GB) | Multi-GPU support: 2-Way SLI, AMD Quad CrossFireX | Features: 1 x PCIe M.2 (Key M)
$59.99

Or

ASUS ROG Strix X470-I
Form Factor: Mini-ITX | Socket: AMD AM4 | Chipset: AMD X470 | Memory Support: Dual-Channel 2 x DDR4 3,466MHz (up to 32GB) | Multi-GPU support: No | Features: 1 x PCIe M.2 (Key M)
$250

I don't plan on going past 32gb of ram... and 16 feels comfy for know
I just want to make sure I'm not overspending on the mobo!
Any suggestions?

ASUS ROG Strix X470-I as it's newer chipset and more suitable for 2nd gen Ryzen, Better support for Power boost and XFR2. Ram also works better on it.
