I guess its fine. The most important thing when it comes to mouse is that you like the shape almost all Mouse now a days has a very similar optical sensor. Software allowing me to change dpi is also important to me.. I play with 1000dpi and if the mouse dosent allow me to change the dpi to what I am used to I would look away because it would take me time to get used to a new dpi setting.
As I play a lot of counter-strike, the mousewheel is also an important thing to me because thats what I use to jump also the mouse1 and mouse2 buttons has to be good.
