If you are serious you need to buy the Elgato. it is the best out there by far, best thing about it is you will never miss anything if you get an amazing clip you can literally rewind and record it!
I second that. I would save up and get a good quality game capture card. I have an elgato and love it. They have some amazing features with the default app.
