Is there an addon that can look at your amour/weapons and advise what to replace it with?

if not is there someone that is talented enough to make 1 for me?

EDIT: this is for WoW. just so you all know. thanks for any help in advance.

on Blizz " Community Site " U can see that in Armory, things like " Equip-Eval " will tell U what any "item" u pick-up will do for U
