Re: Mouse stuttering
My son recently got a Razer Death Adder Elite which runs at 16k dpi. It was going all over the place. While it has its own adjustable settings, the windows mouse settings also impacted on its performance. We set the Razor to 8k dpi and adjusted the speed of the windows settings to a speed that was comfortable to use. He has a decent cpu and loads of ram. Might be worth looking at here too.
