Now if you're planning to go all out and have a cpu block, a gpu block a northbridge block, a hd block, etc... then you could benefit from running 2 rad's in parallel with two pumps. BTW, if you do run 2 pumps and if they will share the same resevoir together then run equal gph pumps. If they're independent closed loops then it doesnt matter.

You're cruisin' for a flamin'!
Multiple rads, even for one CPU wb is fine. It's actually better... because it lowers the flow to each rad, allowing more time for the coolant to 'cool'. The problem is that they will both (ideally) require a source of fresh air, so the whole thing ends up taking so much space, that it's increasingly difficult to fit it in one case.
The benefits are negligeable of course, but with a powerful pump like the 1250, it certainly can't hurt.
As for using two pumps... it's a worthy idea. One of the pumps becomes a booster pump. Not very efficient, but it does work. (pumps in series).
Pumps in parallel would be a bad idea in this case, because these two pumps are very different. (pumps sharing a res)
Pumps in seperate loops: it's easier to control the flow that way. Otherwise, you're looking at the old debate of series versus parallel, with valves and fittings, and so on...
