I game on a 25" 1440p monitor. I read that at this kind of size, you can start to notice (not see, but notice) the pixels if you go with a 1080p resolution, so I went with this resolution as I wanted a monitor a bit bigger in size.
Next time I have to replace my monitor, I may go with a 27" one, but it will still be 1440p.
Please excuse my bad English.
Currently gaming on a PC with an i5-4670k@stock (for now), 16Gb RAM 1600 MHz and a GTX 1070
