Does it matter when to take the Necromage perk for the added boost to the skills of my Vampire?

I keep hearing and reading conflicting statements that one MUST level Restoration to 70 FIRST in order for the skills to get the boost. I would think that I doesnt matter, but wanted to know what you all think of this.

I have yet to level Restoration to 70 on my current Vampire build because I am still in the process of training and developing the characters abilities. She is currently at the following levels:

60 Illusion - All perks taken except for Expert, Master, Rage, Master of the Mind (8 Perks total)

61 Conjuration - Novice, Apprentice and Mystic Binding (3 Perks total)

30 Destruction - Novice, Apprentice (2 Perks)

52 Restoration - Novice, Regineration (2 Perks)

42 Alteration - Novice, Apprentice (2 Perks)

29 Light Armor - 1 perk Agile Defender (wasted perk since I wil be going with Robes) (1 Perk)

49 Sneak - 1/5 Stealth up Deadly Aim (3 Perks)

Currently, she's at level 25 with 3 perks available. Not sure if I should 1) stop everything and focus on leveling Restoration to 70; 2) continue as is in building her skills; or 3) start perking Enchanting (currently lvl 51 with no perks)

What would you guys do?

No it doesn't matter when you get it.

I'm not sure when to take the perk, but I normally try to get perks after Necromage just in case.

i have just recently restarted a new character with necromage in mind: you need to level your resto to 70 FIRST BEFORE you take any of the affected perks.

The exception is eagle eye (which is bugged). If you want eagle eye perk then you must take this before Necromage perk.

I did it in this order. Got Eagle Eye perk first. Leveled to 70 resto (takes ages). Became a vamp (any vamp). Then began selecting my affected perks. This way you will maximise your necromage. This is only if you're aiming to optimise your character.

Personally I think you should do it anyway you want.
