Sword seems too low dps to be worth much.
You are right about the crit damage being worth a lot in terms of DPS. I looked on the AH for weapons and found some good candidates for you.
I searched using the parameters:
Dex 100
has socket 1
Crit hit damage 61
100k max buyout
This gives you items that both have a socket and have built in crit damage (since no one would ever sell a 70% crit gem in a weapon for 100k). This easily gives you options for over 100 crit damage per weapon.
These one I took out the dex and put in 100 vit instead, both were actualy under 30k each
Anyway, lots to choose from, and obviously I dont know your price range, but that's what I would start looking for in terms of AH stuff
