Yes, a rerolled amulet like that would end up similar to how I rerolled my main wizard's amulet.
The ring's rolls are: average damage, split int+vit, IAS, CC, CD, socket. You'll have to reroll both the int+vit in order to get a higher int roll.
All in all, not bad, but sheet DPS takes a pretty big backseat in RoS. You'll have to balance a lot of EHP and/or crowd control to be able to tackle higher difficulties without sufficient sustain. In addition, your eDPS will be heavily influenced by skill bonuses (e.g. Meteor damage, Arcane Orb damage, etc.) and elemental skill bonuses (e.g. cold skills bonus, lightning skill bonus, etc.) that you will have to somehow make room for on your gear. Those bonuses will not show up on your sheet DPS.
Also, just in case anyone's wondering, your character profile will always show your unbuffed stats, so less epeen for everyone to flaunt.
