Overclocking, when done correctly, is definitely a plus. Learn how to do it the right way, select the right components, and overclocking can give you that extra CPU headroom that you need. Having said that, my last Windows machine – a 6-core – was more than powerful enough at stock speeds for extremely heavy projects. I overclocked it when I first built it, then realized I didn’t need the extra headroom, and returned it to stock speed… but the good thing is that I knew I could overclock it in an emergency. I ended up selling that machine as I’ve been transitioning over to Macs in my studio, but I still have Windows machines as well, all of which can be overclocked if needed. Just buy the right parts, and learn how to overclock safely. No need to push it all the way to the bleeding edge, which can affect stability. But a decent overclock is not a problem at all and can definitely help you. Good luck!
