Do you have a need for the mobo water cooling block? that and the Armor are the biggest differences between the two, I haven't found a need for liquid cooling with my Hero, am at 4.6 24/7 (4770K) , 32GB of Trident X 2666, and have a pair of Asus 780 CUs in SLI with the Core at 1098 (Boost 1150) and memory at 1563 (still playing there)
