What software is best for recordings for Youtube?

I just tried out recording my first video yesterday and the quality of it turned out like crap and the game lagged pretty bad during gameplay, when i stop the recording the lag went away, but my keyboard was only telling me that i was using around 60-70% of my cpu... and much less of my GPU... later on i found that my keyboard is giving me false readings, because in CPUz i can clearly see im peaking out between 92-100% cpu usage on all cores during recording of the game, but once i stop the recording i drop down to around 30-40% only....thinking maybe the software im using is not optimized very well.. its called open broadcaster software, found it after watching a video on youtube on doing gameplay recordings and streaming...
