I disagree, with Intel. Video editing is highly threaded, and Hyper threading is not as good as a Piledriver 8 core. Note, I said AMD Piledriver, not bulldozer. So here is my Opinion.
As for gaming, many people have been done in by marketing. Here is the truth, when it comes to D3D/DX 11 or higher, Intel does not perform better than AMD at resolutions 1080p or below, and if it does it is very negligible I mean like only 2% diference, but, in video editing, yes there is much more disparity in favor of AMD's Piledriver. If you game in older versions of Direct X or, you game at resolutions higher than 1080 and every last frame is a priority then go with Intel. Otherwise, for what you want, the FX chip is best.
Z77 will let you push turbo up to 4.1ghz
The Xeon is an i7 with more cache, 100mhz sloer with no IGP and its a lot cheaper
PSu can allow CFX
128GB SSD and a 1TB HDD for slower volume storage
IPS and LED 1080p screen
AMD is also a great choice if wanting a balanced machine.
Memory: G.Skill Ripjaws Z Series 16GB (2 x 8GB) DDR3-2133 Memory ($106.25 @ Newegg)
just scrap that out and get 1600/1866 ram and try adding inside an SSD
I mentioned the 2133 because it has a noticable impact on gaming in AMD's most recent architectures, and the added price isn't that much. But yeah, most definately going the ddr3 1600 and getting an SSD is a better choice. I love SSD's
You should start your own thread but here is a build anyways
M4 over 840 due to MLC over over TLC
670 since you might like phsyx but a cheaper card
Gigabyte motherboard for its better overall build quality and power delivery phases
A cheaper and better looking case (IMO) but you can stick with the 922 or even get an NZXT
You can't sli with this PSU but left it as is (get this http://pcpartpicker.com/part/xfx-power-supply-p1850snlb... if you want to sli)
Cheaper ram with same performance unless you want to do an mem OC (not familiar myself with it)
Mircocentre has the 3570k for a bit cheaper than amazon but is pickup only
cheaper DVD drive
