I use 16Gb of DDR3 on a Z97 mobo.. its more than enough..but as per others, its the 1060 that will hold you back. In my case, with the 1080ti, it carries the system and makes up for the older i5 cpu.Hi there, just wondering if it is necessary to go higher than 16GB of DDR4 RAM to optimally game at 4k? Thanks
