I am a programmers and I am building PC with AMD Ryzen 3600. I will not be doing any gaming on it but need more cores so i choose Ryzen 3600 instead of Ryzen 3400G. I just want it to give 4K output at 30fps. I will be buying a motherboard which will have HDMI port supporting 4k output. Which is the cheapest GPU which will fulfill my requirement of display output of 4K @ 30fps.
