looking for a new monitor to enjoy XIV 1080@1ms or 1440@5ms?

you wont notice a difference between 5ms and 1ms especially not in FFXIV.

This. Even in something like an FPS, you'll still struggle to see a difference, the difference will only increase peoples e-penis length, width and height.

Personally, I'd for for 1440p.
