MCR-QP Stackable Radiator Series Released

I am thinking about running my 2 gpu's in parallel, but from what I have read is that you lose performance because the water by-passes the first block for the most part and goes to the second block. I guess it would help if someone could link me a picture or diagram showing how the water should flow.

that's inaccurate. as long as the pressure drop in both devices is similar, coolant will flow in both.

There is a loss in coolant velocity in a parallel setup, causing a local loss in heat removal capacity, but since pumps having a finite ability to push fluid, parallel setups may become beneficial in many circumstances. GPU cooling is among the most typical candidates for such configurations. By minimizing the overall pressure drop in the loop, you maintain high heat removal where it counts most, the CPU, while keeping adequate heat removal capacity at the GPU's.
