Reason to choose the 1700X - higher stock clocks. Reason to choose 1700 - much better thermals and power consumption, thus better efficiency. All of the Ryzen 8-core CPUs overclock the same to around 4 GHz.
XFR - extra boost beyond single-core turbo - 100MHz for the 1700X and 50MHz for the 1700. Needs to have Balanced power profile in Windows, however that interferes with all-core turbo, hence a disadvantage. In practice, not that useful.
X370 - most expandability, boards featuring this chipset are generally better for overclocking, have better RAM support, and have enthusiast-friendly features. Both SLI and Crossfire are supported.
B350 - in terms of actual specs not that different, but B350 boards do not have as many features for enthusiasts (BIOS code display, on board power and clear-CMOS buttons etc.), lesser overclocking features, and depending on the model, lesser expansion slots and I/O. Supports only Crossfire; no SLI.
First thing you need to know is what resolution you would be gaming at and whether high refresh rate is important to you.
Also, what other things would you like to do with the system. If it's going to be gaming-only, then there are better options out there.
If you want to overclock, X370.
The 1700X is better binned, so might yield a better overclock.
X370 + 1700x
ps. The system will fly in everything, even games, and it will get better and better. Be ready to be updating your board firmware often during the first few weeks.
See this isn't a good way of deciding on what to choose while building a new PC. As I said before, if all you want to do is gaming, then depending on the type of game you have better options.I am going to play For Honor.
Xfire works on at least the tomahawk. I wouldn't see why it wouldn't work on the others as well, but that is the only one I saw that listed it as supported.If it were my money I'd get a 1700, none of the ryzen cpu's like to be over 4 GHz so I doubt "better binning" will get you much extra performance if you manually overclock.
The main difference between X370 and B350 is that X370 allows you to run multiple graphics cards in crossfire/sli (sli might not be on all). Both allow overclocking.
Good question, but I wouldn't rule out a 1700 and a B350. Someone on reddit supposedly got up to 4.25 GHz @ 1.406v on that setup.I am going to build AM4 PC to play game or overclock.
Does anyone know more of what the differences?
What's the different between X370 and B350?
What's the different between 1700 and 1700X?
What's the XFR?
I went the other way. I was looking at the boards, and I was like "I am already spending $140 for the x370 k4, and I need a wireless card, so I might as well buy the taichi for another $20."

Though the entry asrock x370 asrock boards are only an extra $30-$40.
The killer and taichi(not really entry) also come with a m.2 Intel 802.11ac WiFi card, which is $17 on newegg. So, the killer is $135 after MIR, and comes with $17 network card, so it boils down to say $120. Now compare that to the other b350 boards. $100-$110. It's only a $10 difference, assuming you need the network card.

Just for comparison on my Prime X370-Pro with Intel 211T I'm sustaining 110mb/s from my NAS.The onboard RealTek Gigabit Ethernet Lan is working properly as well, I'm getting around 93 to 94 Megabytes per second transfer rates with it from the my NAS (which is about the limit for Gigabit Ethernet).
