I do not understand why you people are trying to be the best through youtube videos alone.
You cannot become the best players nowadays unless you have:
A Razer Naga (deathadder not enough buttons)
A mechanical keyboard (Razer Blackwidow is best for this because easy macros)
$ 300 minimum headset (for ingame sound obviously)
240 hz eizo FORIS monitor
dxracer gaming chair (
http://www.dxseat.com from here, S class is the best believe me)
also gaming shoes like this
and matching gaming socks too
+ 10k dollar pc and op 64 bit script
you need 10k+ dollar pc so you don't dip below 30 fps LOL
