for FPS gaming you want lower DPI high polling rate. 1800dpi is max i would say for FPS gaming.
If you play RPG / MMORPG games then higher DPI is better.
The mouse i would suggest is deathadder, but if you don't want razer go for mx518.
The ms 3.0 is only good because you don't need drivers which is good for lan. BUT if you don't mind using drivers as you won't have no problems with them ignore the 3.0 and go with mx518 or deathadder!
