Hi i am looking to buy a black magic cinema camera doing 2K editing, scaling, and playback. Any suggestions on a build? Ive read the configuration on black magics website but they're not exactly clear or they dont really make it simple. Also im not doing any game playing on this pc. Purely for video editing and theres a slight possible chance ill be doing 3D rendering.

Pretty sick build, an ultimate cpu + 64gb of ram is key for a video editing machine.

Definitely a i7 still going to recommend a 3930k because the more cores and hyperthreading the faster the videos will render.
I5 4670k 4 cores
I7 4770k 4 cores, has hyperthreading makes it count as 8 cores
I7 3930k 6 cores, has hyperthreading makes it count as 12 cores

Partpicker isn't showing it most likely because of a compatibility error, most likely the motherboard isn't a x79.
4770k definitely because it is overclockable, meaning you can increase the speed of the cpu within bios allowing it to perform even better, increasing rendering speeds.
All of these configurations are seriously short on hard drive space and speed, especially if you're using the BMD camera in RAW mode. (Which, btw, is 2.5K, not 2k) In RAW mode, a single stream of 24 fps video for the camera is 120 MB per second; in ProRes or DNxHD, its 24 MB per second. A 250 GB SSD will store around 30 minutes of 2.5k RAW footage, according to BMD- which is, roughly, a little more than one day of shooting. A normal film would be shot at 5:1 ratio (meaning five times as much footage shot as the final product) so a 30 min short film would mean 1.25 TB of raw footage. If you're doing VFX shots, assume that there are multiple layers for each shot, and rendered 3d shots would be rendered out in .exr format and then composited down to a single .exr, meaning even more drive space used for a single shot. To successfully edit the RAW mode video, you need to be able to sustain more than three times that data rate (at three times the data rate, the storage will barely be able to keep up when you render transitions- you need to be able to pull both of the incoming streams from the drives at their full data rate, plus be able to write the rendered transition to the drive) add in seek time on top of that and it needs to be 'more than three times'.
The usual solution for this is to have one drive (or, usually, a RAID) as the 'source' where your raw footage is, and another drive as your 'scratch' drive (where the rendered transitions etc are stored...) some may go further and have another drive as a destination drive for rendered output. (This, and the possibility of SAN use, is why editing applications support different destinations for all three footage drives.)
Your render speeds are going to depend on your GPU as much as, or more than, your CPU. Also, if you're doing major color correction you're likely to use DaVinci Resolve as it comes with the camera- and it only supports CUDA for GPU acceleration on Windows. Premiere CS6 and CC use GPU acceleration all over the place- color correction (including minor adjustments), transitions, etc. So the GPU is not a place to cut corners on this machine. You should be just as worried as to whether your GPU is 'sufficient enough to handle' 2.5 K RAW video as your CPU.

Two 7200 rpm hard drives in RAID as your video 'source' drives unless you want some redundancy. One 7200 RPM hard drive as your scratch drive. SSD for OS and programs. Size is something to look at because the more platters per drive the faster the data rate is going to be. Geforce 760 GPU (Quadro will be no faster and much more expensive, despite the 'common knowledge' that compute is crippled on the consumer cards... it isn't.). 3930K is fine for CPU but you may need to cut that back in order to get the prices for everything else to line up.
I don't know how much you'll really need 64 GB of RAM. If you need to cut it down to 32 GB, do so.
I'd have a better idea for what drives and drive sizes to reccomend if I knew what kind of projects you're intending. If you're shooting commercials, then you could do it all using SSDs. If you're shooting a feature, you're going to need more drive space.

Thanks that makes sense. Although I've heard that the 760 is not good for video editing. Everyone either recommended the 580 or 680. Any thoughts on that?
And I'll be doing pretty much everything. Feature, shorts, music videos, and commercials. Looking to have a versatile independent production company
Since my budget is quite modest, would you say one 7200 2TB drive for footage and one SSD would be enough?
Unless you can recommend inexpensive quality hard drives that i can buy multiple of.
GeForce 760: 1152 CUDA cores, 170w power
GeForce 680: 1536 CUDA cores, 195W power
GeForce 580: 512 CUDA cores, 244 W power
Since a lot of the difference in performance is CUDA cores, not clock speed, the 760 is a good balance between CUDA cores and power requirements. The 580 is quite outdated at this point and consumes a lot of power. Yes, Fermi has better double precision floating point than Kepler. No, video rendering doesn't use double precision floating point (and neither does most of the GPU-accelerated 3d rendering).
Cut the RAM down to 32 GB and put the extra money into hard drives. Use two 3 TB 7200 rpm drives, one as a source drive and one as a scratch/destination drive. If you go with your present disk architecture, you're going to be much more limited by your storage speed than your RAM. Even with the two separate drives, you are going to be limiting your system's ability to process video because your system will only be able to feed one stream in real time- which means that if you make a simple crossfade, the fastest the crossfade can render is 2x real time. Simple color correction will render, at best, in real time- which means 30 minutes of cuts-only video, with color correction (even a simple brightness/contrast adjust) is going to take thirty minutes to render because that is as fast as the system can get the footage- and this assumes that the source and scratch drives are separate. If the source and scratch drives are the same, then subtract the data rate of the scratch files from the drive's speed, subtract some more for seek time, and then refigure how long it will take.
A feature (90 m length) shot at 5:1 ratio (5m of footage per minute of screen time, which is considered a somewhat conservative shooting ratio) is going to need about 3.75 TB of storage space just to hold the raw footage. The thing is, these RAW files cannot be directly edited in Premiere Pro. You'll need to import the files into Resolve, and do at least a preliminary grading on them, then make QuickTime proxies for editing in Premiere. Once you've done the edit, you can go back and conform the footage to your edit, and do final grading in Resolve before exporting into Premiere for your final edit. Yes, this means storing the footage multiple times and yes, this means lots of storage space involved. Another lesson to learn: don't shoot RAW unless you need to.
You are planning on renting your lenses, right?

No, as in the rental facility. You usually have a few basic lenses for yourself, and rent the $3k+ lenses as budget calls for them. A quick glance shows 'serious' lenses for filmmaking with the BMD camera as starting at around $750 and going *up* from there to around $10k. The $750 lenses rent for about $40 a day. Renting lenses and camera gear like tripods and dollies and heads is a 'normal' line item on a production.
