1. Don't get any pre-manufactured water cooling. Very bad idea.
2. Don't ever, ever pay that much for a GX2. That is a horrible price.
3. Just disregard that post all together. That is not the way to go IMO.

By couple of Db-1's, you mean 2 or more? Please explain how this works though. By having the 2 GTX SLI Waterblock, and the D-tek Fuzion V2 Quad Core Insert and the Db-1's, how does this all come together to work. With the reservoir of water with the CuSO4·5H2O (btw I'm a chem major so I know this stuff) and the tubing, does the tubing run through each of these with the water mix and takes the heat out and brings it back to the reservoir or what?

Ok, well you said you wanted 2 loops. Which means you'll have one loop just for your CPU, then one loop for your Graphics cards. So basically your building 2 water cooling systems.
So for the CPU loop, you'll need 1CPU block, 1pump, 1 Res, 1 Rad, fans and tubing. Then for your graphics cards loop, you'll need 2 GPU blocks, 1 pump, 1 Res, 1 Rad, fans and tubing.

So on the GPU loop, it would look something like this:
GPU block #1 >> GPU block #2 >> Res >> Pump >> Rad

Then on the CPU loop, it would be:
CPU block>> Res>> Pump >> Rad

Basically, you want the Rad right before the hottest running part. That way you get the coolest water into the hottest part. Make sense?
Also, another general rule is you normally want to have your pump pushing into the Rad first. I've heard people say because of pressure, but IDK personally. In my experience, I got the best temps going:
Block > Res > Pump > Rad

And the easiest way I can explain it. Is basically your Res holds all the extra liquid. The pump moves the liquid through the blocks. While they are in the blocks, the liquid picks up the heat from the fins within the block, and transfers that to the Rad. Which has air blowing through it so it cools it down.
Does that make sense?
Is that what your were even asking?
( I get confused easy) lol
