I'm looking to buy a gaming monitor and looking at the Asus TUF series.

I want a 27 inch but im not sure what version of this monitor i should purchased.

also not looking for a curved one.

What resolution and hz?

Sorry for the late reply my gfx card is a 1070 so i dont think i can go higher than a 1920x1080 mhz 150+ maybe? etc

still go 1440 but why asus? why not MSI or some other brands.

for monitor info I'd go checkout Monitors Unboxed. https://www.youtube.com/channel/UCDKLZBNM9XZ7pHPZF9D8xDQ
the amount of info Tim gives is way to good to ignore.
