in regards to your specs - this is what we got:

Intel Core i7-5960X Extreme Edition, Octo Core, 3.0GHz, 20MB,LGA2011-V3,22nm,BOX
ASRock X99 EXTREME3, X99, QuadDDR4-2133, SATA3, RAID, ATX
Kingston HyperX FURY Black Series 16GB(Kit of 2) 2400MHz DDR4 Non-ECC CL15 DIMM
Kingston HyperX FURY Black Series 16GB(Kit of 2) 2400MHz DDR4 Non-ECC CL15 DIMM
Transcend 256GB SSD SATA3 MLC M.2 2280-D2-B-M (čtení/zápis; 550/320MB/s)
NVIDIA GEFORCE GTX 980 TI
Corsair CPU Cooling? Hydro Series H110i, 140mm vent.

those parts were about 2000 ?

and definitely use SSD drives or a raid 0

but we got that machine cause we work with up to 5 cams with h264 files with 60 fps - if you only work with one camera, you do not need something like the above - which is despite of watercooling still pretty loud when under heavy load
