If you really want to focus on video editing and file compression, I would reccomend the i7 6800K, it costs €452,01 on this website: https://azerty.nl/8-6127-938171/intel-core-i7-6800k-3-4-ghz.html. If you also want good gaming performance you should get the i7 6700K. Its slower than the i7 6800K in video editing and file compression but not by a huge amount, and you'll have much better single core performance.
