You don't need to build a new PC for playback as suggested. A decent video card upgrade using madVR will playback the highest of bitrate UHD titles in any format like the popular HEVC in any container like iso or mkv as well as full file structure from the index.bdmv file just like a Blu-ray. UHD HDR also. You won't get menus though. For that you would need special hardware and PowerDVD. CPU doesn't matter. The GPU is doing all the decoding and you better get a hardware based one. My CPU is 10 years old, a Xeon. Windows 10 supports HDR, W7 doesn't. W8 might. Simple as that. You don't need a top of the line GPU. A GTX 960 4GB will play ANYTHING, oldest GPU I know of that can. I found one for $125 a year ago. You can invest more in newer but there's no point unless you game or find a better new/used deal. UHD, 3D MVC, HDR, HEVC, 1080p, etc. can all be rendered from the same HDMI 2.0 port. RGB full 12bit @23 - 60Hz is a breeze. Never tried but I don't think Netflix would be a problem. Ripping hardware requirements is a different story. You may or may not need to upgrade. We have no idea until ripping software becomes available, if ever. Until then, everyone is guessing what 'should' be required based on hardware protection that wiz bang software may get around. One thing is for sure, you would need a UHD ROM. Don't get discouraged. Be very careful in your GPU selection and you'll be fine. Tip: If you go NVidia and want complete automation with front ends like Kodi, be sure it accepts 378.92 driver. This is state of the art HDR dynamic switch specific and unrelated to anything else. Nice to see others weighing their options while we wait for the day we might be able to back up UHD's and for convenience, play them on our devices. Until then, we keep using dedicated roms but testing files to be ready for when that day arrives, if ever. Fwiw, other options would be streaming devices and gaming consoles however I've never tried them but know they have limitations in many other areas and it takes an array of them to cover most of the bases. Personally, and imo, given I already own a W10 PC (upgraded for free) and have no desire or reason to use an outdated O/S, I think simply upgrading a GPU is the best and least expensive option if you don't have a compatible one to begin with.
