My 12 yrs old Samsung 226bw is getting more white patches day by day, tried some methods to rectify it but still no use.
Years back like to play strategy games so a TN panel with 60hz and R9 270 2GB could still satisfy me. Recently trying more on FPS and racing titles. Felt the 226bw struggles to keep up. So thinking of replacing it with a larger 27" 144hz panel.

But i'm not sure to get a 1080p or 1440p.

Current setup:
i5 4670 3.4Ghz
Sapphire RX580 8GB
Hyper-x 16Gb DDR3 1600mhz

Correct me if Im wrong,
If 1080p, can get better frames, higher details but less sharp with a 27" screen
If 1440p, can get sharper image, future proof but lower frames, lower details

Currently eyeing on:
1080p: Acer VG270P
1440p: Acer VG271UP

Also I'm unsure of the smoothness/performance if let's say the gc is only pushing out 60fps to a 1440p 144hz monitor.

Hope sifu here could shed some light and suggestion on models.
