Please stop calling it a 4170K then. It's an FX 4170. There are no K's in the FX lineup.
Now that everything makes sense...Definitely try and get the hexa core 1600 as that'll last you longer especially if you plan on upgrading your GPU in the future, the difference between X370 and a GOOD B350 motherboard for the average user is nothing. Both chipsets allow you to overclock.
