Update: I ended up going for a 32" IPS 4k Acer Predator for £800 as prices have come down with black friday. Now after using it extensively I can tell you I am not that happy about it. All the things that people talk about are true, namely things like artefacts randomly appearing, bleeding in all 4 corners although mine is not suffering from it massively, and then the headache of setup with limiting fps, use for what game what, gsync not working properly with some games (CS GO - I've tried everything on forums/reddit/etc still have tearing!)
But maybe the thing that bothers me the most is that for normal use and for my desk I find this monitor too big and not easy on the eyes at all compares to my previous Dell IPS even in normal usage(so there must be some flicker or something as clearly my eyes hurt even the next day - and yes, I use it from the correct distance). Not to mention that with my mac paired with is nowhere near as usable on native resolution as a 2k monitor (constantly have to fiddle with settings to get it into something usable).
So this monitor is going back because of all these problems that just should not be there for a monitor in this price-range. I feel like I paid a lot for something that is not delivering and not convincing me.
Next option on the list is to go for a 27" IPS 144Hz and give that a go with my GTX1080 and see how will be doing. Not too many option in this range either, it is probably coming down as said in other threads to 3-4 monitors (asus, acer, viewsonic with prices ranging from £500-800 again). Giving that a go now and if again disappointed with the same quality control ie artefacts and bleeding that will go back as well and either I swap my GPU for a Vega and try a Freesync monitor or give up on this altogether.
My personal conclusion after spending over £1100 for an upgrade from 2k to 4k gaming/desktop usage is that the benefits are not worth it. I somehow wish I spend the money on something else and stayed with GTX970 and my dell with its 5ms+ response time that I've got used to. Yes, some games look amazing on a static image if you compare things side by side but when once you start playing you see the defects faster with this monitor rather then the things you gain.
Another things bugging me: I've just upgraded the nvidia drivers last night and it screwed up my League of Legends Gsync setup (which was vsync turned off in game, all max, and fps capped at 60 and gsync turned on from nvidia control panel). Now with the same settings LoL is ruined, barely playable - felt slow, laggy, blurry almost from the tearing! I had to turn Vsync on to even make it barely work.
All this stuff is unacceptable from a pricey setup like this and for this kind of price-range premium. Don't get me wrong, I am all about paying for quality as I do believe you will have long forgotten about how much you paid when you get quality and if you get inferior products the flaws will be a daily reminder of what you have paid. Seems like we are taking 5 steps forward and 7 steps back when upgrading tech nowdays.
Maybe it is just me or the way I was settings things up and reading online? BTW all of this happened on a fresh copy of windows, fresh drivers etc
