Damage is not everything despite what most people seem to think (because if you're dead that big fancy DPS number is actually 0!!).
I just cleared Act 2 yesterday with only 18k dps. I had 6.5k armor, 400+ resists, and 37k life though. You want gear with Int, Vit, and All Resists mostly. Other good stats are Armor, %Attack Speed, and the crit stats if you're not using a channeled spell build.
I use now: magic two handed mace 841 danage ( 772-1097) attack speed 0,9 + socktet +14-28 damge
I see 2 things in the AH:
1. magic two handed axe 1126 damage ( 902-1350) attack speed 1
2. magic spear 790.2 damage ( 441-876) attack speed 1.20 + critcal hit damage increased bij 63% with this weapon I gonna use my magic source +40-225 damage +68 Vitality
