Sounds like prosumer stuff, basically high end motherboard ($290) and latest extreme processor (165W TDP, 16-cores, 32-threads)? I would think this would all be overkill for BI, use it for gaming and your old rig for BI unless you are planning to run some number of cameras I wouldn't dream of.
I am using Win7 laptop, i7-3520M @ 2.9Ghz and 16.0 GB RAM (vintage 2012, TDP 35W, 2-cores, 4-threads), and with 3 cameras and motion detect it runs 15% CPU and 4 GB RAM usage (only 500 MB of that is BI).
