when u plan to overclock i would recommend the 1700X. any reason for disliking the nighthawk rams? if u r against LED, i get it. there is not much difference between g2/g3. to be more precise, i think the g3 was optimized for latest gen intel cpu sleep states. so i think a g2 will still be good for ur ryzen. also, y a taichi mobo? it was stable and had good reviews when am4 was new. with the aega 1.0.0.6 update, almost all am4 r stable n good.
so including the changes i said above :
