Hi, Currently have a cheap fifine USB mic:
I want something better sounding that doesn't pick up my keyboard. I will be using is for gaming mainly, and it would be set on an arm mount.
Youll need a mic with directional pickup. Shotgun mic.
Do you have a recommendation of one?
You'll be needing a dynamic mic. I suggest the Audio Technica ATR2100 at $70 or a Shure SM58 at $100.
Those don't seem to be directional mics, won't they pick up more sound?
Dynamic = directional
Condenser = omnidirectional
These are both dynamic mics, which means they only pick up sound in a cone in front of them. They were designed to be used in a stage setting, so that the mic doesn't pick up the audience in the background or other instruments on stage.
