After going through a few TN panels with G Sync, I would never recommend buying the PG278Q. Unfortunately TN panels and G Sync tend to have more problems than not, and if you look online most users have gone through multiple ones of the same monitor before they had one that worked properly. From what I have read and the experiences I have heard, the IPS panel doesn't have nearly as many problems, but I haven't tried that model yet myself to try it out. I will most likely give that model a shot next since we will be sending back the Q soon. - I'm starting to wonder if G Sync is all hype like it's made out to be. Hopefully you guys have better experiences. :)
