Oooo a settings thread.
I'm using a Razer Deathadder 1800dpi edition @ 500hz on a Steelseries QcK+ Fnatic edition, sensitivity is roughly 33cm/360 with mouse acceleration disabled.
My monitor is just a 22" ASUS 60Hz (bad) one, but I'm saving up money from a Sunday job I do alongside my studies to buy a 120hz BenQ monitor, because that stuff actually makes a difference yeah
The sensor on the Deathadder is absolutely beautiful, although I ran a polling rate test and it flickers from a stable 499hz input down to about 470 when I make very long swipes over my mousepad. I guess that's what I get for using a low sens.
Also I built my own computer, had it for almost two years when it was considered fairly high-end.
I can run anything I want on any setting, but due to me starting university next year I haven't found much time for gaming, although I was hugely into QuakeLive before. I plan to play the new Elder Scrolls Online game when it comes out, though.
EDIT: Just played a round of quake with a wmo 1.1a, so damn nice.
