I had recommended an addon to many of you call reforgenator. Cliffton pointed out that while reforgenator works most of the time, it doesn't necessarily take into account diminishing returns.
There's a great web interface called Ask Mr. Robot that will automatically find the best reforges for your gear, as well as recommending gear upgrades and telling you what is BiS.http://www.askmrrobot.com
Have a look, check it out. You mind find some of the gear you swapped out and put in the bank might be better than what you just upgraded to.
