Slow response times? If you plan to play games like; Far Cry, GTA 5, Crysis, The Division and many more, 3-4ms response time does NOT matter. If you plan to only play competitive CS:GO then you want 1ms response time. You NEED 144Hz refresh rate no matter who the fuck you are or what you prefer to play. If you want high quality 1440p, then this: https://uk.pcpartpicker.com/part/asus-monitor-90lm00u0b01370 otherwise just get 1080p 1ms
