which cpu should i get?

Hi 🙋 everyone As the title says I'm building my first gaming rig and I decided all the parts except the CPU and I need your help to choose between the ryzen 5 1500x or 1400 The reason why I'm confused is the cache size on each on so I will be greatful PS I live in Jordan and there is huge price gap between r5 1600 and 1500x so therefore I won't get a 1600
