I am building a dual opteron rig and and need to water cool it. However, all the dual cpu water cooled rigs I have seen so far do not cool the gpu too. What is the best way to cool dual cpus and a gpu, whould this be and internal or external water cooling system (either is fine, whichever has better performance)? What pumps resivoirs and other parts of the water cooling system would recommend to cool the cpus and gpu as much as possible? Thanks for any imput or suggestions.
