4790K versus 5820K "budget" builds

Go with build 2, but get 16 gigs 1600mhz or 1866mhz, get the cooler Master hyper 212 EVO, if you don't mind a bit of noise then stick with the EVGA brand 970

i5 4690 + Asrock Z97 Killer + MSI GX 970 TF - is enough

Since what you'll mostly be doing, as far as I understand, is video editing, I'd go for the 5820K. It'll give you more flexibility and faster rendering times.
When it comes to multitasking, the new Intel chips have proven to be way ahead. You can search a video that NCIX put up on YouTube on this matter, comparing these processors we're dealing with here.
Good luck.

build one.
ditch that water cooler and get the noctua D15

get another PSU from SeaSonic like the m12ii 620w

The i7-5820K will give you an option for processor upgrades where the i7-4790K will likely give you none. The i7-5820K needs 4 DDR4 dimms for best performance (quad channel memory controller). The memory below is the same cost as the two dimms you had before.

I'm running a GTX-260 that I had lying around in the meantime and have never seen it runs as good as it has in the past. Also using a XION Black Colored Gaming Case for $39.99 which is of great quality for the price; It has water hose ports in the back if you wanted to water cool, its ready. Note: I went with the Micro-ATX MB and Case to save weight and space. I'll upgrade the video later.

Memory is overclocked @ 2667 on 1.36 volts perfectly stable. I even lowered the command rate to 1T and all the timings down to 14, and it works with superiority. My CPU cores are also overclocked from 3.3 to 4.5ghz (i7-5820, Vcore 1.36v, 1.920 input volts). So it seems this memory works great considering I'm pushing my system significantly further than normal. I went with a an ASRock motherboard and I love how this G.Skill blue colored memory matches it perfectly! I didn't really need the Killer LAN so I went with the X99M Extreme 4. This MB also tied for #1 in OC performance, offers a speedy M.2 slot, and is priced very well. I didn't even need water cooling with the awesomely quiet and cool Noctua Fan.

Ran Passmark 10x sequentially and temps rose slightly, maxing out after 7 runs and I stopped at 10.
Avg Temperatures (Idle): CPU = 37C/98F, MB = 37C/98F
Under Full Load: CPU = 76C-83C (Max of 10), MB: 41C (Max of 10)

So I am blasting this thing with performance and staying well below 105C and see no benefit to water cooling at this point. I'm scared of water anyway. 8 ]

Haswell-E overclocks better from what I've seen so far around town...
