So I bought an AOC 29 ultra wide screen 21:9 2560x1080p monitor. Want expert opinion before my return date expires. Should I upgrade to a Asus 29' 2560x1440p monitor ? Or should I return it and buy an Asus 27' 1080p but 144hz monitor for 200$ less on CL? Is 1440p a big difference than 2560x1080? Is 120hz gaming noticeable ? I am running on i5 3570k w/ gtx 670 ftw signature 2...no overclocked on either.
