Loop order!!!

[Darcvm]

Hi girls an guys,

My question is really simple, which loop will provide the best cooling performance? Here is the data and a picture.

Components to be cooled:
CPU (will be overclocked)
Two GPU's (will be overclocked)
Motherboard

Loop components:
All rads are 480 mm
The pump is high performance
All blocks are high flow certified, so no restriction

Your help will be much appreciated.
