I will suggest you to go with amd ryzen 5 2600x or i5 8400 both are the good CPU. If your main aim to just play game then I5 8400 is the best CPU for you and if you want to do some mutli core tasks like video editing then go with AMD ryzen 5 2600x. Also if you are planning to overclock the CPU then you can get a overclockable version of the CPU.
