I have an overclocked I7 2600k and I have EK blocks coming for my 2 7950's which are in crossfire. Currently I have an EK XTX 360 and I am going to add either an XTX 120 or 240 to the loop as well. Question is - will the 120 be enough or will I need a 240? 
All rads will be running Scythe GT's. The rest of my rig is in the sig below.
Advice as always greatly appreciated.
