This is plenty of INT but an awful, awful DPS on the weapon. To be honest, as a wiz you should not even bother with Act II, Act III unless you have AT LEAST 40k.
Just to demonstrate, i have GF/MF gear on which significantly drops my DPS which is now approx. 30K - with GF/MF gear.
What you need, is FIRSTLY and most importantly a good weapon (for Inf i recommend 1H + Off) where the 1H should have AT LEAST 830 if not better DPS. No APS on the weapon please because it screws up stats. The main weapon should also have a decent amount (150ish) of INT because you do not want to sacrifice INT for a few more DPS. Its always better to get a good DPS main wep but ALSO having INT on it.
(Before Inferno i had a slow 2H, but i really started to like Wand + OH + wizard hat)
Reason: Wand, OH and Wizard Hat provide additional arcane power (A MUST!) especially if you get a fast 1.40 speed wand - because this will drain Arcane power very, very quickly.
As an off hand, this also needs to have + Max Arcane power and preferably good damage anywhere in the 50-200 ish or better range, preferrably INT as well.
But then DPS is not everything, you need resists out the *** and armor as well. I'd say 400ish resist one everything, 5000ish armor, 1700ish INT..
Skills are essential..magic weapon (for boosting DPS), energy armor with force armor...etc..etc.. <--- however, all this being said Act II+/Inf will still be incredible hard. But those stats should get you *at least* started.
***
I dont think that going out full armor (with energy armor etc. +40%) i once had 8000 ish armor and 600ish resists will do any good if it sacrifies too much DPS - because it will virtually impossible to take stuff down, right now it is already impossible to take down treasure goblins (with 3 people simultaneously DPSing!) probably because my current 30k is not enough!
If people cant take down a treasure goblin...it should give an idea about what DPS would be needed to even halfway make it through the game....i'd say my above figure of 45k might not even be enough, at least for II/III...
