My 1600x performs quite well, especially after the multicore recompiler was added. In BOTW I get framerates between 40-60fps with these graphicspacks: FPS++, 1440p and high res shadow. I have it paired with 2833mhz ddr4 memory and a GTX 1070 and the CPU is also oc'ed to 2.75ghz

Other games like Super Mario 3D World and Mario Kart 8 run pretty much flawlessly even at 4K, so it's safe to say that it can handle the CEMU emulator pretty well.
