There are 2 ways to farm in Diablo 3. Gold Find or GF and Magic find or MF. I have done both and suggest magic finding. The best Diablo 3 magic find spots can be amazing if you get lucky. You make a more consistent income gold finding, but can hit the lottery magic finding. I have found several items worth over 15 million gold. I have also farmed with 300% base gold finding gear and have made up to 600k an hour.
