Possibly - but remember dual wielding doubles your int or str damage bonus (each damage bonus is applied to both weapons). What's more, the character sheet only shows the average damage-per-weapon for dual-wield, so your actual damage is twice what's shown on the character sheet.
But crit increases also apply to both weapons, so if you've already doubled your dual-wield damage (as shown on your character sheet) and it's still less than the crit bonuses, then you should obviously go for the crits...
