My CPU goes at about 55% while using 9 GB RAM. I guess I will have to look into the speed of my hard-disk.

@JanBerktold - are any of the cores maxing out?  It is possible that the playback isn't able to run multi-threaded as well.  That could potentially cause a bottleneck even without maxing the overall available CPU power.

<p>I am attempting to edit the videos I've recorded with a GoPro Hero 3 in Premiere Pro CS6. However, the preview window jumps, is slow and not smooth at all. As this pretty much makes video editing impossible, I was looking for a solution.</p>

<p>Are there any settings in Premiere Pro CS6 which would fix this or are you guys able to recommend me another program for Windows 7 which has a comparable features?</p>
