I wouldn't mine BTC in the case of only having access to a video card / cpu for mining. If you really want to mine, though, there are other currencies such as Litecoin (LTC) that offer more fulfilling mining opportunities for the average person.
This is what I don't understand. What do you mean by "fulfilling"? Shouldn't it be a matter of net profit? How much you make in your pocket at the end of the month, quarter, year?
Please, enlighten me, how much money will I be making per quarter in Litecoin vs Bitcoin?
Since everybody's mileage may vary, I would suggest using a profitability calculator. There are plenty of open ones available here on the forum, as well as ones like the one on bitcoinx. There are also calculators that compare different crypto currencies, etc.
