Intel Z87 and Haswell 24/7 OC Guide @ techPowerUp

The overclocking I do is focused on borderline stable performance and while this type of overclock gets the most performance it is only useful when doing competitive benchmarks.  When you look at 24/7 stability you must consider the impact of long term overvoltage exposure and cooling.  More often than not simply dialing back your OC is the solution

Overvoltage can damage the CPU and cause it to degrade while cooling can impact stability and also cause various components to prematurely fail.  The TechPowerUp article touches on these facts and preaches that you should buy the best. (duh)

Make sure to grab from popcorn and a fresh beverage, you'll be reading for awhile.

Recently purchased a new Haswell-based CPU only to run into an overclocking nightmare? Looking for some tips to get a bit more out of your chip? After pushing the limits for several weeks and ending up with more than a few dead chips, we've come up with a guide focused on 24/7 overclocking with Haswell!

My suggestions are a little simpler.
1) Buy the best as a good motherboard goes a long way.  Most any board featured on this site is a good candidate. 
2) Get good memory.  With Haswell 2133Mhz is a starting point, faster is better. 
3) Get a factory overclocked video card, DX11 games are dependent on a good GPU. 
4) Get a high powered PSU, the higher the rating the lower the heat output. 
5) Get good cooling in your chassis, large cases tend to cool better.
6) DIY Watercooling is best
6) When it comes to actually overclocking the system keep voltage changes to a minimum,  On the CPU you can often get 500+Mhz just from multiplier adjustments without voltage (limited to X and K type).  Set memory to XMP and enjoy yourself.
