Edit: Let's take a concrete example. How much more more OC headroom would a reference EVGA GTX 780 with a waterblock have over the same model on air? Would the price difference of the waterblock make it smarter to instead purchase a better version such as the Classified?
GK110 has a lot of OC headroom, so in this case going with water cooling would allow you do do things like flashing a custom BIOS and really upping the voltage. In theory, you could probably go from around 1100 on air to 1300 on water, depending on how hard you are willing to push your chip. Going with a Classy would be very beneficial in this situation, the chips are capable of 1400+ on the core but on air they tend to reach their thermal limitations before their silicon ones.
