4K for what: gaming, image editing, office? The KalmX specifications can be found here:

Probably too weak(?) for current games
On my old PC (Win 10 Pro, mainboard Z87-K, Intel i5-4570) the KalmX served an LG 38" monitor, but only for office and image editing! On my new PC (Win 10 Pro, mainboard Asus Z-390-A, Intel Core 8700 (without K) I have not installed a graphics card; the graphics performance of the CPU is fully sufficient for my needs (office, image editing).
