Some of the people here stated that it's the weapon dps that determines your spell damage. That is incorrect. It's the weapons damage that determines your spell damage. Case in point, I found a 2 hander that had 100 less dps than my previous two hander, but the difference in damage was exponential. My previous weapon had 900-1300 damage, the new weapon was 1200-1600 damage. The higher the base damage on your weapon, the harder your spells will hit. Also to note, as you level up and your weapon damage increases, finding items with +damage will not have the same effect as +int, as intellect scales better with higher weapon damage. Consider swapping out your red gems in your weapons for +crit damage gems instead. These scale exponentially better as you level as well. Just my two cents.
