Modern processors with boost configurations are rather complicated about "thermally throttling". These days with AMD's stock coolers you will be able to at least get the sticker speed on the CPU even at 100% load for a sustained time. Chances are, you'll actually get some % more speed than the sticker as it will usually continue to boost as long as power delivery and temperatures are stable. So even with an entirely stock configuration, a better motherboard and cooling system will overall net you more performance. This is without doing any traditional "overclocking" and just going with the settings designated with the CPU and motherboard. This same idea also applies to most of Intel's parts as well.
