Farming: Act III quest 7 (Kill Azmodan and the map) mentioned by newt0n.
Act III quest 7 (kill azmodan). Do this on nightmare or hell. The key here is to stack gold find and gold radius. An average set will cost you 500,000g and net you 200% gold find and 50 yard radius. You start the game and teleport to Core of Arreat. You then farm until you get the checkpoint on the stairs at the end (1 run should take about a minute). Leave game, resume game, clear to the waypoint this time. Rinse and repeat. With the gear listed and the run time listed you should get almost 300,000g an hour.
Correct me if anything is wrong
