27 inch 2k OLED or 32 inch 4k OLED

Hi guys, I've just upgraded my pc to 9800x3d and rtx 5070 ti.

Should i go for 27 inch 2k OLED or 32 inch 4k OLED. I don't play competitive and fps games. Mostly single player and some MMORPG or MOBA. I will be using the monitor for work too, mainly for ms office and autocad.

I am currently using 27 inch 2k IPS monitor. So which one should i go for?
