recording a youtube video question

I wanted to try recording me playing a game on youtube. That is easy enough. Here is my question , how can i record game sounds and my voice as i play the game. I am using bandicam, it works best on my system.


Use Camtasia studio 7. Its good soft for video recording.

Yeah i know but costs like $350.00 compared to bandicam whcih cost $40.00


If you have a mac I find sceenium to be a good option
