Hi guys, Would love abit of input and advice on a new monitor, Im currently running a 23" IPS full HD which is nice but looking at a bigger panel 27/28" Ideally i would like to up my rez too 2560x1440 and 120/144hz Obviously the Asus PG278Q ROG Swift ticks all the boxes except price but with me running a ATI 290x G-sync wouldnt apply and have been reading about flickering when running at 120/144hz on my card. Not sure that i would be just ****ing money away buying it if i couldnt use it to its full potential but people say they dont even use G-sync. and is gaming at 120/144hz really that good? or worth waiting for Acer XB270HU?
