I use this:

110k dps with sharpshooter fully stacked, but it's so low because I'm also running 127% magic find. I've completely ignored survivability in this set. 15.7k hp, 140 is my highest resist. I'm a total glass cannon.
I currently farm act 3. I start on the quest "The Second Heart" and work my way down to Cydaea. If I don't get 5 stacks of valour in the 2 tower levels I go to Arreat Crater level 1 to finish it up. Kill spider lady, then go through the core and kill Azmodan. Currently sitting on 73 million gold from selling drops on the AH.
