I went with this monitor although it doesn't have gsync (only freesync):
MSI Full HD Gaming Red LED Non-Glare Super Narrow Bezel 1ms 2560 x 1440 144Hz Refresh Rate 2K Resolution FreeSync 27" Curved Gaming Monitor (Optix MAG27CQ)

I was searching for a gsync compatible monitor myself but it seems to be holding out just well.
Same here, don't think I'll ever be going back unless it's an oldass handheld platform. It's nuts how these machines are 3.5k+ (at least that's what my price tag was for my build). Twice the ram, 100+ more watts from PSU but we're otherwise the same.
