need suggestions/recommendations for gaming monitor upgrade. i'm looking for a multi-monitor setup; so want some borderless devices. current budget is ~45-50k/screen. currently deciding b/w either of acer predator and aorus FI27Q

Not sure about the acer one but please don't go with aorus. You can get all the spec in Asus VG27AQL1A with 6-8k less. I'm using this monitor for last 9 months and very happy with.
