Thanks for the infor.
I would not go for a X79 build,the 2011 socket is a dead end, although the i7 4820K has a larger L3 cache than the i7 4790K it's base speed is a lot slower and for the level of editing you plan, tthe higher speed will serve you better.
I will configure the build on CPP to get best prices for parts.
Do you happen to be within a reasonable distance from a Micro Centre for Pick up parts. > http://www.microcent...es/default.aspx

The Cyberpower pc looks pretty good at ;first glance,but I think overpriced as some parts are pretty basic and cheap, Azzi keyboard/mouse, headsets, case, some parts not required, water cooler, internal Hub,, flash stick. Read the reviews on Newegg. > http://www.newegg.ca...CED&Pagesize=20
Your intention to have a local shop build it for you is a good idea as you can get better parts/performance for the money.

The GPU is weak for a high end gamer.
The HDDs are too big, use three 1TB drives, especially for using FRAPS.
Consider this build, and we can tweak as the case might not be to your liking. Click on the estimated wattage, towards top right.
