Plz which monitor to get?? 29 ultrawide vs 27 144hz

the first one has freesync technology, for amd gpus

you have nvidia gtx card, the first one is discarded just there

the msi, is freesync too and msi is not known for doing gaming monitors

you need to search gaming monitors ultrawide curved with gsync technology to take advantage of the 1070 you have, lg iirc has none
 


g sync is very expensive for me. but which one is better? msi is bad>?
 
why are you going to buy a monitor for a technology you don't have that is mant to be used with that technology

on that list of parts, it is expected to have a expensive monitor

from those two, ignoring the freesync situation, the lg, msi is just entering the marked, no idea how bad it might be
