Question about Dell Alienware Aw3418dw

You can, but it makes no sense. This monitor has 120Hz (overclock) with G-Sync support. With GTX 1060, even if you switch all details to minimum at 1440p resolution, you won't even get 60 FPS in most modern games.

To get the most out of this monitor, you'd need something like 2080S.

So better buy something cheaper, without G-Sync with 1080p resolution, or a better graphics card with this monitor.
