Hardware is already so fast that overclocking really isn't needed anymore, I think we do it now-a-days for the fun of it. Also overclocking isn't what it used to be, now anyone can do it if they can navigate a BIOS. I think its up to software now to catch up and take advantage of how fast our hardware is today.
Hell, I had this 4770k at stock for months when I got it, I just couldn't find much of a reason to overclock it. Everything ran as fast as I needed it too already.
Even on a 120hz monitor? And might not stay like this for a long time. Do you think it could be useful in the futur?
