Anyone into building PCs as an alternate hobby? I built one few years ago now, but I forgot which website I went to in order to determine whether all the parts I had were compatible. Looking to possibly upgrade the GPU in my current one. It's an old NVIDIA 1070. Hard to believe we're up to the 40 series cards now. It looks like I need a 30 or 40 series card to be able to run HDMI 2.1 output to 4K screen.
