Its all personal preference dude.
As a general rule, lower is better, but not too low.
Ive played on extremes like 2000dpi x 1.6, and as low as 450 dpi x 0.49 (1.4m per 360 lol)
Ive settled on 450 dpi x 1.2 ingame, which is pretty much a 270 from edge to edge of my qck heavy. ~53cm per 360
Fast enough to flick with a scope at med/close range, but slow enough to pick heads at range.
1) No drivers lol, IME 3.0
2) 6/11
3) 1.2
4) 450 (ime can be argued that its 400, but it moves same distance as my DA, and more than my 518 @ 400)
5) 53cm per 360 (more important than numbers, as it varies with alot of things).
Also, to those of you with a new DA, after some testing, the DA doesnt perform as well as it should at 3500 dpi, or 900.
Use 1800 or 450 to get the most out of your mouse.
