Hi guys. I'm runnning a Ryzen 5 2600X with a Asus ROG Strix GeForce GTX 1080 8GB Advanced.
I play mostly FPS games, and Open World games like Skyrim and Fallout...I'm looking for a 27'' 1440p 144hz G-Sync monitor, and for now, i only liked these 2:

Predator XB271HUA

Dell S2716DG (I can get this one on sale by 500€ and it's actually prettier.)

I Know Dell it's a TN Panel, but will that make such a difference, for example, in Skyrim ? I dont want to give more than 650€ for a gaming monitor, will i be fine with the Dell?
I need opinions. Thanks!

I have the Dell and it's great! Can't compare it to others, but IMO it is a great monitor for the money.

I'm trying to decide between the Dell S2716DG and the Asus Rog Swift PG278QR
