4K 120Hz or 1440 165Hz

Recommended Posts

Hello all,


I am looking for a new high end monitor for gaming and have narrowed it down to two options. 



27" ASUS ROG Swift PG278QE Monitor, TN, 2560x1440, 165Hz, 1ms, G-SYNC, 1000:1, 350cd/m², HDMI/DP/USB



27" Acer Predator XB273KGP Monitor, IPS, 3840x2160, 120Hz, 4ms, HDR, 1000:1, 400cd/m², HDMI/DP, G-Sync Compatible


Is the 165Hz worth giving up for 4K? Also would my system be able to drive 4K at high settings? 


This is my build:


CPU: Ryzen 9 3900X

CPU Cooler: Corsair Hydro H60

MoBo: ASUS ROG Crosshair VIII Impact X570


RAM: 32GB Corsair DDR4 LPX 3600

Storage: 500GB Corsair MP600 SSD

i don't think the 2080 super can push the 4k 120. unless you plan to upgrade to the 3080ti, i'd go for 1440p. plus, at 27in, there won't be that much of a difference

Thanks! Appreciate the advice and saves me some money :)

Personally i'd go for the 4k of the 2. 120 to 165hz just isn't useful to this mere mortal. 

At me or quote me, I want to hear your opinion.

I can confirm that my 2080 Super cannot hit 4K 120. It can hit 1440p 165 in most AAA games on high settings, so I would go with the 1440p 165 Hz option like boggy77 said.

Thanks everyone for the replies - given that my computer likely can't run the 4K I have gone for the 1440
