The motherboard directly will not give you more performance or frame rates, but it can limit the performance of the components attached to it. Getting an x570 motherboard will provide you with an advantage as they come with a better chipset and VRM, which is likely to give more overclocking potential to the processors, and Ryzen CPUs are factory unlocked. In comparison, chipsets like x470 and others are also good as they support these processors after a BIOS upgrade.
