It's been my personal experience that most of the time, you do tend to get what you pay for. Regarding your example, I've been using ASUS motherboards for many years, quite of few of them, and I always overclock. Even though I've tried other boards, I've had extremely good luck with ASUS for overclocking, as well as reliability and stability. More expensive motherboards also tend to be more feature rich, which I personally like. I tend to stick with what works for me. The "better" brands cost more, but it's usually worth it in the end.
