Rog - why the 7700k? My impression from the tech community was that its barely an upgrade. The first result in Google for i7 7700k is
http://arstechnica.com/gadgets/2017/...y-lake-review/ where they call it what happens when Intel stops trying because they have no competition. In addition, when info came out on the 7700k, the price on the 6700k went up $50 that day.
