http://www.overclockers.co.uk/showproduct.php?prodid=BU-003-CM&groupid=702&catid=23&subcat=1257 does this have on the fly dpi changing.
Yes the CM Sentinel has on the fly dpi changing, but it's not the best mouse by any means.
Sidewinder X4 and a G500.
By the way, when gaming do you use the WASD keys or the cursor arrows?
WASD so Sulid are you recommending the g500 because it's logitech or something else because the gigabyte m6900 has almost the same specs.
