Ben I would counter that flow rates above 1.5-2GPM are sometimes still beneficial but no longer practical. Let's assume that you are willing to increase radiator size and fans to keep water temp constant and remove that from the equation. Even still, the cost/performance benefit for going from 0.5-1GPM is usually large, the benefit for increasing from 1-2 is much smaller (and may be completely offset by pump noise), and the step from 2-3GPM is probably not worth it to water coolers.
