The curve for the Swiftech 6000 comes to mind - there seems to be very little additional benefit as flows increase.

Probably not. Even if the flow curve is perfectly flat the transistion from a 1046 to a 1250 looses by just .3C (remember we're dealing with a 9 w pump here, which isn't a huge problem for a large-ish radiator). If theres even a slight downward curve on the C/W per flow curve, the block will pick up the couple thousands of a C/W needed to offset the 7.5w gain.
Of course, if you assume a small enough radiator, all bets are off
