I think I'll wait for sales (Black Friday). I've been looking at the Zenith Extreme since it was announced, but it's overpriced in my opinion. It looks worse when compared to the other motherboards currently available price wise. I don't see $100 better than the Asrock Pro Gaming or $200 over the Taichi.
I've downloaded a few motherboard manuals to go through, in the meantime, I'll watch/read reviews and see what new motherboards show up (like Asus Strix). I'm going to try to order a pair of RX Vega 64s' with the money since they might be a little harder to come by at MSRP in the future.
