New to being a Mage

[Triumph]

Pure INT or x INT:25 SPR.

Some empower Magic Missile cooldown with 5 points. There are enough spells later on to get by without empowering. Same goes for Fire Bolt.

Magic Blast + Fire Ball: 5 points for power.
Fear: Duration, optional cooldown.
Inferno: Cooldown.

Optional:

Chain Casting cooldown.
Stifle duration, optional cooldown.

Oh, and use level 1 spells. The damage bonus from higher level spells isn't really worth the SP consumption. If you want to use higher level spells, then feel free to. Magic Missile and Fire Bolt should remain at level 1 regardless, due to increased cooldown at higher levels.

Most of your empowerments may not occur until your 50s. My suggestion is to save your points, for there are unreleased skills right now. All empowerments should be empowered with 5 points for maximum effect.
