I use Fraps and it works really good, 60+ FPS, and no lag. I really looking forward for your YouTube channel, and once you get it up and running I will be glad if you message me the channel.
I use Nvidia Shadowplay and I love it! It has an awesome feature that records the last 10 minutes of my screen. So even if I forget to hit record I can hit a hotkey and boom I have the last 10 minutes saved. I can then just use Windows Movie Maker to chop it down and upload it to YouTube.
