In 2015 I had 2 4k60 monitors, and as long as I setup screen composition in the nvidia settings, everything was as smooth as silk and as sharp as a magazine in Linux, and still is.
In 2015 I was in CLion day in and day out and my gpu was only a laptop gpu with 2gb of vram, so it definitely maxed out my gpu then, but still was as smooth as butter. I had to worry about my computer heating up at the time.
Today I'm on a desktop with a 980. I'm sure it's inefficient, but doing anything in the desktop, like watching youtube in 4k60fps uses about 15% of the gpu according to nvidia-smi. With all my apps running, when I'm not training neural networks, my desktop + firefox takes between 1gb and 1.5gb of vram.
