I found this just a little bit ago and thought I would place it here. This will allow me to book mark this for future reference.

Hell Mephisto has 94,320 life in a 1 player game. Assume he has ~50,000 life after
Static Fielding, your merc tanks, and you�re usually �sweetspotting� (orb explosion inside
Mephisto's graphic).
1) 20 Frozen Orb/Cold Mastery minimum band: 267 dmg
-115% cold resist modifier vs. Mephisto�s 75% cold resist: 372 dmg
imperfect 12-shard �sweetspot� hit: 4,469 dmg
50,000 / 4,469 = ~11.18 casts to kill
2) 20 Frozen Orb/Ice Bolt/Cold Mastery, minimum band: 366 dmg
-115% cold resist modifier vs. Mephisto�s 75% cold resist: 512 dmg
imperfect 12-shard �sweetspot� hit: 6,149 dmg
50,000 / 6,149 = ~8.13 casts to kill
Basically, you waste 19 points in Ice Bolt to save yourself 3-4 casts of Frozen Orb to kill Mephisto.
Also gonna add in the lil bit about FO vs Blizzard
----------------------------
There are 17 shards in the final "pop" at the end of a frozen orb. These 17 shards carry the listed damage in the LCS. It is these 17 shards that will do the killing for you and not the numerous that are released along its path. Basic comparason between 1 cast of FO versus 1 cast of blizzard on a single target. Both FO and Blizzard will be left un synergized for this example. This will demonstrate that for 1 more point, you can get a much better spell.
LvL20 Blizzard does 655 to 711 in damage per falling shard. Has a mana cost of 42. On a really good cast of blizzard, you will hit the enemy 2 maybe 3 times. For this example we will go with your elite skills and say you hit the critter 3 times in single cast of blizzard. Not importantly, it has a cold duration of 4 seconds which is penalized in NM as well as Hell.
LvL20 Frozen Orb does 262 to 267 in damage per shard. Has a mana cost of 34. On a really good cast of frozen orv, you will hit the enemy with 12 or 13 shards from the "pop" at the end as well as a few from the shards that fly out on the way there. Again, we are going to assume you are elite and say you hit the meanie with 16 shards total from one cast of Frozen orb. Also not importantly, frozen orb's cold druation at lvl 20 is 27 seconds.
So this critter we choose to shoot at. Lets say he has 2K life and 50% cold resists. Lets see how much damage he is actually going to take from each spell.
BLIZZARD
-----------
3 x 683 ( average damage ) - 50% ( cold resists ) = 1024.5 [ blizzard would round this down and you would only do 1024 damage ]
FROZEN ORB
---------------
16 x 264 ( average damage ) - 50% ( cold resists ) = 2112
OMG it is almost double in damage. We have not even factored in the cold mastery here. Now if you fully synergize blizzard, I will agree that it does loads more damage. HOWEVER, for making a durable/go anywhere sorc, choosing the cold spell is a no brainer.
Any ?'s just ask!
