I don't have a squaky voice, and my accent isn't that bad.

Thanks for all the reply

Thanks for the feedback, and I started already, but I recorded in portuguese. I will try in english, but I need to practice.

Hi, my name is Sergio.
I'm 14 years old and I'm Portuguese.
I want to become a game commentator, but I need some help.
First of all, can I record with these specs:

CPU: AMD Athlon(tm) II X2 250 Processor
CPU: Speed 3.0 GHz
RAM: 8.2 GB
OS: Microsoft Windows 7 Ultimate Edition (build 7600), 64-bit
Video Card: AMD Radeon HD 6700 Series
Features:
Pixel Shader version: 5.0
Vertex Shader version: 5.0
Dedicated Video RAM: 1.0 GB

Also, should I do commentary in my main language, portuguese, or english? I can speak english pretty well, but my accent is not so good.
And are Fraps, Audacity and Adobe Premiere Pro CS6 good software? My dad uses bought Fraps and Adobe Premiere, 'cause he uses them.
And please don't hate. I wanna to do something I like for a living, so why not start now? If you know Syndicate, you know he used to work at McDonald's, but he's a great commentator. That's pretty much what I wanna do.
