Okay so many people think one way or another is better.
I've tested both of them.. they both perform identical really.. I've found that restriction caused by CPU waterblocks will inevitably be the reason that you will see no change in performance (combine that with the fact that flow rates is not a huge factor in water cooling)
BUT THERE IS ONE BIG, BIG FACTOR THAT I'VE FOUND THE HARD WAY THAT MAKES ONE BETTER THAN THE OTHER
Basically it comes down to flow rates within the water blocks to prevent stagnant water.
The following pictures are of two identical waterblocks mounted to identical video cards using identical, parallel tubes to transfer water from one video card to the other.
As you can see, there's clear buildup of gunk on the end of the GPU Waterblock, my assumption is this is where waterflow is the slowest, and as a result of running them in parallel, I believe its created stagnant water...
I used Biocide (PT Nuke and a silver coil) and had 1-2 drops of water-wetter in my 1 gallon mix that was used to fill the loop. The green stuff is probably my UV GREEN Dye from Feaser One
For this discovery, I'm suggesting to stay with GPUs in serial setup.
Hopefully this helps some of you!
PS: I believe this might have also caused my GTX 285's to die on me
