Is the 3310 any good? I feel like there's no guarantee on which mouse sensors are flawless these days. It always seems like there's some weird quirk or bug. The Avago 3310 seems to be the successor to the 3090, and I haven't heard much bad about it; however the Avago 3090 also has been proven to be one of the better if not best sensor at that time - especially considering that they don't make those older Deathadder sensors anymore (S3888 or something?).
genericapplesauceThe 3310 is considered a 'perfect' sensor. Most implementations have less jitter and higher perfect control speeds at similar or higher DPI settings compared to a 3090. It also has some neat features like adjustable LOD. Zowie use it in the FK1, Steelseries use it in the Rival, Mionix in the Avior 7000, Roccat in the Kone Pure Military and Corsair in their M45.
