Should I record my voice with a gaming headset or a pro mic?

I have a YouTube gaming channel. I've been recording with my new Apple Earbuds that come with the iPhone 5 or the iPod Touch 5. I'm travelling this summer so I will buy some stuff.

I will buy the Razer Kraken Pro (green with mic). Should I also buy the Blue Jeti or should I keep my money and record with the Razer Kraken Pro mic?

I'm small and just starting on YouTube. I have like 120 subs.

If it matters, I upload Minecraft (mainly), COD, Skyrim, Left 4 Dead 2, and maybe some League of Legends and other games in the future.

When I watch a YouTube video, if the presenters voice is clear and crisp I will stay a bit while longer and listen to them. However if the voice is fuzzy and poor, no matter what the content is, it will put me off from the channel even if what is presenting is something that I will enjoy.
It is in your best intresst to use a pro microphone because that will draw in more views.

Depending on your Budget I would get a Blue Yeti With a pop filter Thats what I got, but no pop filter yet. It is a really clear mic and lots of youtubers use them.
