So if your heatsource is 70 Watts, you can expect a CPU temp of about 13 degrees C above your coolant.
(I think that's right...)
If you were able to double the flow rate, your CPU temp would only drop by about one degree C.

More comments added: doubling the flow rate also means quadrupling the head. The Iwaki MD-20RZT won't quite get you there. (by Since87, now there's a familiar name )

I think I may faint, someone is finally beginning to realize that substantailly increasing flow requires a lot more pump power yet yields only small benefits. What's the world coming to? All sarcasm aside, I think you left out the impact of doubling flow rate on the radiator. Though minor, it also has some small, positive effect.
Bill's data let's you pinpoint the "knee" in the performance curve for a block. Working to get flow above this point is (pun intended), pointless.
