So, it's pretty obvious that Ryzen CPUs completely destroys all Intel CPUs when it comes to rendering and various other non-gaming functions. It's not even a contest. Which I really need because I use Maya a lot.
And all of that for 3-4 times less price.
Is this not a good time to switch, or...?
Probaly not the best time, lots of updates are coming, from bios to software even windows, it does look bright the future for it though, i would wait two months more at least so most of the bugs are settle, none the less, for pure rendering purposes, it seems a winner.
But, not a single ASUS mATX board has more than 1 chassis fan headers
The X370 seems only available on ATX atm, i think we will see in time come to micro atx, but seems the options atm are B350. If i were to move to Ryzen right now, i would go with ASRock X370 Taichi AM4
, recently reviewed by Techpowerup ASRock X370 Taichi (AMD AM4)
and got a prefect 10, also reviewed by other sites with very good feedback, even newegg user reviews almost perfect scores. If you are not into ATX, and want to stay mAtx, look into ASRock AB350M Pro4 AM4
it has 2 4pin headers, CPU_FAN1 and CHA_FAN1, that should be autodetect, can do either pwm or voltage control, the third header CHA_FAN2 seems 3pin, this if its like mine, should be a pure 12V header and no control is available.
there is some weird notes about DDR4 RAM frequency not being supported for Ryzen CPUs
There are lots of bios updates being released for AM4, memory compatibility is one of the most comon updates on bios revisions, but my recommendations is search for the QVL list, or memory that has been tested and buy that, its much easier and safer. For example here is a QLV for the Taichi
and for the AB350M Pro4
I'm not even sure about the M.2 standard.
I haven't seen any issues with m.2, but check user reviews i bet you can find one that work out fine with the motherboard you chose.
