How about if your main GPU is AMD? - Obviously W10/11 supports multiple drivers to be installed, but would the additional power draw be the same?
Also I'm guessing if CPU is Intel, then could use iGPU on that? (I'll be sticking with AMD CPU for the foreseeable, but good to know!)
Had considered something along those lines, but really hate the idea of running an HDMI cable out the back and back in!
I assume so, as the motherboards Front HDMI out is wired for the CPU's iGPU. It should not make a difference for make of GPU. Years ago there was something about AMD Crossfire with iGPU, but I don't think that exist anymore.
The power consumption is reasonably high, peaks @55W (idles at 28W) as well as added heat. All it is doing is running Wallpaper Engine, and usage spikes to 100% every ~10 seconds.
100% worth running an extra cable back out and in, IMHO.
