1440p 144hz or 4k 60hz?

[Soger7]

I have 2x 980 Ti's and am currently playing on 1080p 60hz.
What would be the best thing to buy? I have never experienced either.

Thank you

1440p @ 144 hz.... Acer Predator XB270HU, to my eyes is the best gaming experience available today.

How about this one https://www.komplett.dk/asus-27-led-g-sync-rog-swift-pg278q/838757

Predator is:

Cheaper
Faster
IPS

It's actually the first IPS panel I have ever recommended for gaming . The combination of G-Sync, 144 Hz and ULMB makes actually gives it less lag and ghosting than the TN Swift. And of course it has better color and viewing angles.

All things considered we felt that the Acer XB270HU performed the best in these specific tests. The response times were slightly slower than the Asus ROG Swift PG278Q and BenQ XL2720Z, but the benefit of that was that there was no overshoot on the Acer, whereas the others showed some moderate levels. The Acer also has a native blur reduction mode (ULMB) and G-sync support which we will look at shortly. One other thing to note here is that with the exception of the Asus ROG Swift PG278Q these other screens can only support a maximum 1920 x 1080 resolution, and so there's a huge jump in resolution and image quality when extending to a 2560 x 1440 panel in the XB270HU. You get the not-to-be-underestimated benefits of the IPS-type panel as well from the Acer, with wider viewing angles and a more stable image appearance compared with the TN Film models. Overall a very impressive performance from the XB270HU.
