This raises quite a few interesting questions and tradeoffs - how do you handle ugprades (i.e. yearly upgrade to latest/fastest CPU) without taking down the standby box? Have 3 boxes? How about instant handoff? I guess that would require running the second box as a slave, so both boxes are running harder than they need to... Does running one of the old FX-8350/70 at 7+ GHz have any benefit, or is it offset by the per-tick improvements of newer CPUs? It's weird to think of heavily overclocking stuff in a non-gaming workload for me... stuff like chilled coolant and instability suddenly has completely differnet factors to consider.
