If gaming is the main reason you are looking at building a new system, the AMD Ryzen 7 1700X stands up to the Intel i7-7700K in nearly every game we tested. This shows that either processor will work great in a gaming system. The AMD Ryzen 7 1700X though, has the added bonus of the extra cores/threads allowing you to do more multitasking while gaming, especially when it comes to doing things that can take advantage of the extra cores and threads.
