Flow Pattern

I'll start off by listing what I'll be cooling:

Athlon XP 1700+ White Water
Abit NF7-S Rev 2.0 Northbridge
Chaintech Geforce4 Ti4600 GPU

Here's the cooling equipment I intend to use:
Eheim 1250
'86 Chevette Heatercore
Dangerden GPU and Northbridge Blocks
Either a Cascade or a TC-4 CPU block (can't decide if it's worth the cost difference yet)
1/2" Clearflex 60 tubing

What I'm trying to determine is what will be the best configuration to achieve greatest flow. Should I run the CPU and Northbridge in parallel and then run from that to the GPU - kind of a parallel/series configuration - or would it just be better to run them all in series? I have read quite a few back posts here, but I haven't seen many doing all 3... Any help would be appreciated.

I would run:

RES
|
PUMP
|
RAD
|
CPU WB
|
GPU WB /parallell/ NB WB
|
END LOOOP

Running all stuff in series will KILL you flow. The split loop over GPU/NB would be best since none of them really generates a ton of heat, the lower flow won't kill performance.
