If you have a BofA account you can use their porfolio to track credit cards, bonuses, checking, savings, mutual funds, stocks etc.
I like Google Finance for its simplicity.
There are a couple of other websites which I have heard of you might want to try.
MorningStar, Yodlee, etc.
I personally use Google and BofA in conjunction.
Bottom line, you should always keep a track of your assets relative to the amount you actually put in out of your pocket.
