Guys need advice for a gaming headset! Help!

- Your rig: Desktop
- Budget: <RM300
- What type of usage: Skype video calling and gaming specifically. Will not be using for music or movies at all.
- Headphone/ earphone type: Over ear
- Other requirements: Mic quality is of top importance. I wanna make sure my voice sounds clear, no static at all, etc.

I'm considering Logitech G230, G430, and Razer Carcharias.
