A smaller inlet does not boost water velocity through the block, but it will boost the water velocity where the water initially enters the block. As a result of splitting the flows and using the small inlets, you would probably see decreased cooling performance as a result.

IMO, the best way to do this is:

pump -> rad -> wb -> gpu -> nb -> (res - optional) -> pump

All in-line, all 1/2". This gives the highest water velocity throughout each element in the system. As long as the GPU and NB are low pressure drop blocks, you should not see flow rates suffer much at all, and in fact, maybe no less than if you did the separate 3/8" split approach with the extra restrictions that 3/8" fittings provide.
