Need advice on watercooling pump

[Amur]

Hi all,

I'm planning on watercooling my system for the first time. I need a pump that will be good enough for a CPU, GPU and two radiators in one loop, keeping in mind that i will be overclocking both the CPU and the GPU.

My setup is:
1. intel 6700k
2. Single 980TI
3. 240mm dual fan radiator (60mm)
4. 240mm dual fan radiator (30mm)

I need to get a pump as well as decide on the tubing size.

DDC or D5 will be fine.
