If you have ruin or a similar talent that increses spell crits to +100% then just double it.
So, on a shadowbolt unimproved by +dmg gear (assuming about 700 damage) one percent of +crit gear is worth the same as about +3.5 damage on that spell. If you have Ruin, it's worth +7. If you do have +dmg gear, we'll say you're throwing 1000 damage shadowbolts, +1% crit is worth +5 damage, or +10 if you're specced Ruin.
So, it becomes a balancing act. The more +dmg you have the better +crit is, but if you sacrifice too much +dmg, your crits will not be as good. Now you know the formula, on a per spell basis, to determine the optimal configuration!
