I recently bought a Corsair 800D case and am, gradually, plucking up the courage to watercool 
Am currently cooling the cpu with a Corsair H60 and do not intend to change this in the near future.... but see below *
It's the matter of how best to cool , as silently as reasonably possible , my Asus 7950 Top gpu which has my attention at the moment
and I have decided that cooling with water is the way to go.
I've checked the EK site and have found the full cover block I will go with and I've got 2/3 Apache fans ready to blow through the radiator but would appreciate advise as to which rad and pump to go with.
Also not sure if I would be better served to build a loop which can , when I'm ready, cool not only the gpu but also the cpu * (i2700k @4.3 - which I would be looking to get to , at least, 4.6) OR it would be better to build a seperate loops ?
