The idea is to have a water system on the PC where I can cool the GPU, and If I need to upgrade the GPU, I would not need to update the water system, only the aqua computers water block.
I prefer to leave the CPU cooler as it is.
I know there is a big difference in performance.
The reason I did not choose the Fury x is the fact that the 480 is a newer card with 8GB, and it is just a card that will be accompanied by AMD Vega or whatever will be the most powerful card they will release in the future. I always wanted custom water cooling for the GPU, pluss it makes it as quiet as possible at all clock speeds.
