optical's are better for fps gaming because of the negative/positive acceleration issues with laser mice.
I played with a logitech g9x for years until I read the sticky threads on OCN about negative/positive acceleration.
It was very hard for me to pick out a mouse that I liked.
I could not decide between the Steelseries ikari optical or the razor deathadder 2013.
So I bought both.
Since you stated you were using a magicmouse I am assuming your using a Mac?
Mac GamingRazer Synapse 2.0 is available for mac here.

Steelseries engine is available for mac as well
http://steelseries.com/support/downloadsIf you plan on updating the firmware on a steelseries mouse you will need a pc for a few minutes.
For the FPS mouse fix for MAC OSX to disable acceleration read this thread..

m_customaccel_exponent "0"
m_customaccel_max "0"
m_customaccel_scale "0.00

I use 1.0 in game and control my sens with the dpi adjustment from synapse.
If you find that you can not find a in between because it only allows steps of 100 dpi at a time then set your dpi to the lower value and fine tune your ingame sens to compensate.
