In Cataclysm, entry into heroics requires an average ilvl greater than 328. Instead of linking to individual items, I will simply link to the wowhead search page pertaining to that item slot, so you can compare them with each other. I’ve also pre-emptively excluded spirit gear, as the stat is pretty much useless for mages. If you’re a Shadow Priest looking for a good list, click on the desired link anyway, and change the settings so that Spirit is removed from the filter, and is added to the stat weight. Enjoy!
Armor
Weapons
Off-Hand
Neck/Finger
Trinkets, and a pre-raiding loot list to come.
Frost is the New Black 
thank you so much for this. /salute
Is it just me or is there a lack of variety in the icons of the new Cataclysm armor?
I am under the impression that palette-swapped items tend to have similar icons.
For all mages please look at this for pre raid:

you should add http://www.wowhead.com/item=61329 … facerollable in 30-60 minutes.
This is a great list, thanks for putting it together!
One thing I have noticed is that cloth gear seems to be almost free-flowing from heroics. It’s got to the stage very early on where there’s nothing I want to buy from the JP vendor any more because heroic loot has it covered. The only bits I’m missing at 346 is a cloak, bracers and trinket, but I can’t buy these for points anyway. Most annoying.
