I find that overclocking provides little value. Overclocking graphics to gain an extra 10 fps at the cost of 20 degrees hotter; 100fps isn't good enough for you? Or overclocking your CPU so you can what, crunch SETI faster?
There is simply no real world bennifet to overclock components.
Sure, I'll admit I appreaciate the overclocking crowd- I love the cooling gear. I like to get my PC running as cool as I can, stock. Which means I am never concerned about burning up a component. In fact, there is some evidence to support that compenents willl run faster if they are cooler at stock ratings.
