Not good enough to make T5 or any other helm with a meta socket worth using. And that's with fire mage where the 1.5X crits become 1.53 before they're multiplied by 1.4 due to ignite, so the effect for any other caster will be even lower. That's with crit rates at the area of 32-38% or so. Other gear doesn't matter (except for the amount of spell damage needed for 1% DPS increase).
