CPU has little to do with decoding or rendering when using madVR as we apply it. Instead we use hardware architecture in the GPU and its vRAM and take advantage of it with drivers and software like madVR with LAV filters to unharness it. How much oomph a GPU can output allows scaling options in madVR to be determined. Scaling options are also a user preference. What you may like, someone else may not. Scaling options range in intensity. How much unbridled fervor you want to hand to your display is up to you. If you desire a more intensive scaling option and you cannot achieve it, you would need to increase your GPU capabilities. Also consider your display, especially 4k. It applies scaling algorithms too and very well at that. So does the Kodi internal player for titles madVR may not be needed which is user subjective. You have a nice setup. I wouldn't change a thing until down the road when it might become necessary like UHD ripping. Today it isn't. My Xeon X5690 CPU is 7 years old fwiw. Much of the point of this guide in the 1st place was to help users achieve the ability to play anything with a simple GPU upgrade and setup providing they have a PC of some sort already. Imo, it's a worthy option vs multiple streaming boxes that will need replacement as new things are introduced. I'm considering putting up pics of my various scaling profiles to help others with madVR scaling if there's enough demand from others. Basic settings are already included.
