Best Game Recorder?

I want to know whats the best game recorder. I just tried fraps and there is no audio and its pretty choopy or laggy. When i play the game its fine tho but the video is pretty choppy.
Whats a good game recorder that wont interfere with my gaming and will come out the best?

Okay, you gotta set Fraps up to your sound card, not a mic. Just make sure you got your latest drivers. Also, make sure you got the frame rate set to what your games frame rate is. Say your game's is 30 constantly, then set fraps to 30. If that doesn't make it better, than tell me and I'll find you one. But other than fraps it'd be Gamecam. But it's hard to find a working cracked Gamecam.
