I currently have the default keyboard and I don't think it is as good as a mechanical keyboard. A mechanical keyboard has a faster processing time then a regular keyboard. I want the buy the SteelSeries 6G v2 Keyboard - wired - US.
Lol just found out I have a mechanical keyboard but this one has been around in the family for like 5 years lol. I still die most of the time and the keyboard is pretty load so if you type fast, don't get one as it will annoy others lawl. I'm pro though so the keyboard doesn't really affect my gameplay, only the mouse and mousepad as I can imagine the person killing me with a better one.
