I recently moved my dvr install from nas to a Linux machine with an i3-6100...much faster at commercial detection and processing. This helps for remote streaming as it more quickly frees up the cpu while doing transcode and stream.
I have a nvidia GeForce 1030 I could put in this Ubuntu unit...would that perform any better, or free up cpu, over continuing to use the skylake 530 igpu? I am assuming I will need to install the proprietary nvidia drivers. I can actually leave both gpus active, I think.
