your settings look good so far, thats how your mouse should have been set to in order to work well with the xim
high dpi and a polling close to xim3
here is an important info that you might want to consider though
your deathadder has the sensor placed in the middle of the mouse, that is different to your g700 which has the sensor in the upper part of the mouse
just turn the mouse around and youll see what i mean
this will influence your aiming, if you are used to mice with the sensor in the upper part a mouse with a different placed sensor will feel odd to you
as if the mouse isnt precise as you over or undershoot fairly often
if that is the case i would advice you to go for the g700s
