I have an HP desktop with i5-4590S integrated graphics 4600 at my work place. I recently got a 27" 4k display to replace my 27" 1080p old one. The new monitor seems somewhat laggy in desktop use although it is running at 60 Hz. I also have a new HP Ryzen 2200G PC. I am wondering if it is worth moving to the Ryzen if it means better 4K experience? It is a major hassle.
