Hi 4Kanyone?
I have a Panasonic GH4 which shoots superb video and I use PD13 to edit the resulting 4K material.
My machine copes very well with the heavy burden of 4K, and comprises an i7 4770T CPU with integrated HD graphics 4600 ( I have no dedicated card. My RAM is 16GB, but if you can have more, get as much as you can.
However, no matter how powerful your machine is you will no doubt experience stuttering, jumping and freezing on the timeline due, in the main, to very high bitrates. This can be very frustrating, but there are ways to get around the problem. You can use PDs own shadow files which unfortunately are very slow and can in some cases take hours to process before you can edit anything because you have to wait for ALL of the clips to process before you can start editing.
There is a very much faster way but slightly more complicated to use, see here.

Now even better and much faster again is the "new kid on the block" Magic+PD. It's a very fast way of converting files with a lossless codec that's results in problem free editing and faster rendering times too. The final results are fantastic .
I thoroughly recommend you have a look at this thread and consider using this great little free program. It really will speed up your editing experience.
