Depending on what games you play, you will want to adjust the balance of power between the CPU and GPU for best results. I haven't personally used the full gamut of Ryzen CPUs, but it seems to me that a 1200 might be a little weak. If it were me, I'd probably choose a R5 1500X even if I had to reduce the graphics card to a GTX1050Ti, but if your games are very graphically demanding, you may not want to do that, especially since I can always upgrade the CPU later, for less than the cost of a graphics upgrade.
