I'm going to be using my computer for not only office work which consists of using excel and keeping inventory and keeping info for business but I will also be using my computer as a network video recording system. I'm not sure what set up to go with let alone the CPU. What I do know is that I'll be using purple hard drives for the cameras a regular old hard drive for the work files and then a small 60gb ssd for windows 10 and the NVR software (geovision) I know I want to use intel for CPU I just don't know which one to get. (Cameras will be running 24/7 on a 2 monitor system)
