@angkuy, i couldnt agree more than what you've mentioned. it is a fact that pc enthusiasts or overclockers shares a little percentage in the the market.
what i can say is that, the bottom line to this is:
1. "how much budget" and "to what purpose" are you going to use your setup.
2. to what extent is your heart's content seeing your rig going into the limits
3. your satisfaction that your rig runs faster over your neighbor's
