Scotty's post (above) is correct, The 980 is not suitable for h265. If you want UHD 4k discs to process as fast as BDs, you will need to upgrade graphics hardware and may want to consider a higher-horsepower platform in general if you do a large quantity. Below are the MINIMUM requirements for UHD Ripper on the DVDFab website:
- Windows 10/8.1/8/7 (64-bit)
- 4GB of RAM and above
- 200GB of free hard disk space
- A 4K UHD Blu-ray Drive
- For the 4K HW Acceleration to work, you need:
- Either the CPUs from Intel Kaby Lake series and above;
Or, the video cards from NVIDIA GeForce GTX 1050 series and above - Live Internet connection required to register DVDFab (little network traffic used)
For equivalent to BD-rip performance, I would recommend
- Intel 8th gen CPU i7 or better
- nvidia GTX 1080 or better
- 8GB RAM or better
Note that these upgrades will be good for everything you do on your PC.
