Mouse stuttering in CS:GO and Far Cry 4

I've just got a new System (i5 4690K, 16GB RAM, MSI GTX 970) and I'm expiriencing some weird mouse lag in certain games. To visualize, I've made a quick video:

I've tried several other games (FS:X, Arma 3, Space Engineers) and theres no issue there. Also no issue on the Desktop. I've turned off Windows mouse acceleration, tried V-Sync and no V-Sync with frames limited and unlimited in CS:GO, and tried turning off raw mouse input in CS:GO.

I also tried changing the polling rate of my mouse (G700) to 125, 250, 500 and 1000 which led to no change. This hasn't happened on my old system and It's also not happneing on my Mac with the same mouse. I have the latest Nvidia drivers (347.09). Frankly, I'm kinda lost.
