If you are looking for anything over 60Hz, my suggestion would be to wait.
 
Something you may consider, get a really cheap 4K for the time being. I purchased two 28" 4K Upstar monitors. They were super cheap and do 4K @ 60Hz. I picked them up for $329 each from Fry's but Amazon has them for $349 w/ Prime shipping. You could easily pick one up now until next year and then turn around and sell it on Craigslist or something similar: http://smile.amazon.com/dp/B00SX4WQ2A
 
I regularly get 54-60 FPS in all of the games I have been playing lately (AC: Black Flag and Witcher 3). I have yet to dip into GTA V.
 
Just my .02

Thanks mstoll23, for all that info.
 
I read alot of buyers on Newegg of the 270HU had the same experience as you did.
 
So i earlier purchased the NewEgg Premier as i'm not taking a chance on a bad panel and then
paying the shipping cost to return it.
 
How long is the delay from sending bad your lemon of a monitor to when you get a newer one?
 
 The monitor you mentioned, the PG27AQ looks sweet, but the wait has been killing me since i got the Titan-X, to get a 1440p/4k monitor.
 
 And i'd wait for that one, but since i won't be sli'ing this Titan-X(as i don't want micro-stuttering issues), even on a lesser demanding game like GTA:V, i'm getting drops below 40fps, and from all the g-sync reviews i read, it works best if the fps is 40 or higher.
 
 Now for say BF4, i get 60fps in 4K(<--dsr on my 1080p) but for most others, i'm getting 30-45 on average, on max settings[no AA].
 
 So this 4K thing is a nasty tease as one Titan-X is landing just short of that 40+ fps mark.
 
 Also, i do alot of VR gaming and i don't wish to switch this older 120hz 1080p TN, back and forth with a new 60Hz. 
 
 The 270 panel has some great perks except 4K of course, but i'm kinda scared off a bit with the QC from Acer.
 
 I'm thinking of taking the chance on that 270HU 1440p IPS panel and then go 4K
in late 2016. Or whenever the top one gpu from NVidia can push 4K/60(avg)
 
 The TN panels i'm staying away from as having one now, the colors are bad, the blacks are weak..ect.
 
 And while i mod GTA:V alot, i don't want to handcuff myself with other games that are more demanding(ie..Cryengine games or even games like FC4) as i doubt even with the 1000 series from nvidia in 2016, we'll see the top gpu hit that avg 60fps in 4K.
 
 I used to be happy with 30fps..lol, but now i have to have a near locked 60, at the least.
And i don't need 120/144hz, but it sure helps for VR and i know most games i'll get a solid 60fps in 1440p.
 
 Plus windows 8.1 is still not ideal for 4K with it's fonts. [ie  Origin ]
 
 And if i go for a 4K this year, i'm going with a 48" Samsung 9000 as until OLED's drop
in price by 1/2 or more, that will hold me over. And it's pretty future proof with low input
lag(22ms) and was reviewed highly for gaming. [it has 4:4:4].
 
 I have a Plasma now but of course it's 1080p and the next jump up is 4K, of course.
 
 But for monitor wise, i got that choice and i'm probably going to risk getting that Acer 270HU panel.
 
 I just hope it's not a lemon of a panel..lol
 
 Thanks again!

OP, I just shipped off the Acer XB270HU back to Newegg today. It had either dust or a scratch underneath the screen at the bottom left. Also there was a blotch of un-evenness toward the bottom center of the screen. I did take some time to adjust the display to my liking prior to sending it back, and the colors are awesome. It is a fantastic monitor. The quality issues are still there with the Acer. I requested a replacement, I think it'll take at least a couple weeks to get here. The RMA went to CA but when I ordered the monitor it shipped from IN, so maybe the replacement will also ship from IN.
 
I am giving the Acer one more shot and if it sucks I'll take the plunge and buy a Dell 2715Q 4K monitor. It is 27", IPS, for $699. I may just order the Dell and compare them both side by side. I suggest checking that one out as well. Dell's warranty support for these monitors is great. 1080p + DSR will look nowhere near as good as true 4K.

1080 to 1440 is a massive jump... a much bigger visual to the eye jump than 1440 to 4k is.  Just my opinion but I'd go with 1440p instead of 4k.  I've been gaming on 1440p for nearly 2 years now and a friend has a newer 4k monitor that I have looked at.  I see no reason to move up considering the difference isn't nearly as much as I got when i moved from 1080 to 1440p not to mention i can't get desired FPS in 4k

For someone who has 1440, going to 4k may not be worth the jump.  But for those of us still rocking 1080 do you still think we should go 1440 or 4k as either would provide that huge difference for us.

I returned my 270HU to newegg because of issues with the QC as well.  I have Premier.  They got the monitor back through UPS in three days after shipping and I had my refund within 24 hours after that.  I actually decided that the high refresh rate wasn't a big deal for me.  I may be an exception, though.  I also hated the shiny black bezel (though I could have sprayed it with a coating). Because of all that, I didn't go for an exchange.
 
I have also debated on a 4K GYSNC IPS panel.  Tired of waiting on that, though.
 
I have been waiting, too, for the 21:9 monitors in 3440X1440 with GSYNC.  I love the format in my 29" monitor at 2560X1080.  The Acer X34 (formerly the XR341CK) should be out in a couple of months.  The ASUS will hopefully be by the end of the year.  That is significantly less pixels than a 4K, and I am hoping that my single Titan X will be effective as I struggle with the idea of running SLI.  Having said all that, the Dell u3415W is a 21:9 3440X1440 that can overclock to 75Hz.  It doesn't have GSYNC.  It does, however, have a price tag of only $809 right now on newegg.  It has been sitting in my cart for two days.  I really liked the GSYNC, but that ends up being a $500 add with this sale price as the X34 is supposed to cost $1299.  Just not sure I want to wait and/or pay that premium.

Keep us informed.  Many people struggling with the same thing you are.  Reading anything from people on this is a boon to decision making.

I have used 4K and used DSR.  DSR does definitely help image quality, but no display can show more pixels than it has.  4K is beautiful and is absolutely better in image quality.  Period.  It just isn't necessarily feasible in all situations.  And some people are obviously more affected by lower frame rates than others, which would be a huge consideration in 4K without a doubt.

That helps me also in making a decision.  Its just hard not to go to 4k, I fully admit its that "this is new, this is the best, why get something that isn't the latest and newest" part of me that's driving my decisions here.

 
Why?  The answer is because the latest and newest still isn't ready yet.
 
I'm with ARMYguy on this.  I prefer 1440p at 144hz with a nice crisp 1ms response time.  Things look remarkably silky smooth with these specs and lesser specs are now noticeable to me.  I tried 4k a few months back, but the 60hz refresh disappointed me.  Simply dragging around an open window on the desktop at 60hz versus 144hz was proof enough.  At 1440p it takes a good graphics card to deliver performance due to the high refresh.  But your TX could push that along just fine.
 
When 4k gets the refresh rates up and we have graphics cards able to deliver 4k at solid refresh rates, that's when I will go back to 4k.
 
I ended up with a ROG Swift.  Yeah, it's pricey but it delivers.  On the other hand, if you have a card that can push 1440p along at 120 or 144hz with equal FPS, G Sync becomes less of a "must have" feature.  So although I believe G SYNC is like icing on the cake, you could theoretically save money there. 
 
If you simply MUST have 4k, plan on SLI and find another TX.  Turning down the eye candy as some others do is not a solution to 4k in my opinion. Dropping to 60hz and losing eye candy just isn't my cup of tea.

Well I'm not saying its a valid reason to get 4k I'm just saying its often instinct to buy the latest thing out and the rest be damned kind of thing, I'm sure we all do it from time to time.

 Thanks guys for all the input you have given, as i do appreciate it alot. :)
 
 After days of going back and forth with the 1440/144 or 4K/60 decision, i finally opted
for the Acer IPS 1440p G-Sync panel, as in most every demanding game i play(ie GTA:V
,Far Cry 4, Dying Light..ect) i'm not reaching 40fps on a constant basis, and for G-Sync
to work well 40+ is the min. And there are alot of dips when those games are maxed out[
except AA] to under 30fps.
 
 I got caught up in the 4K 'drama'..lol, and since i'm not going to SLI my Titan-X[as i don't
wish to have micro-stuttering issues], 1440p is a nice sweet spot and with 144hz output
it adds even more as i do alot of VR gaming. 
 
 Also, in using a TN panel now at 120hz, it would be hard dropping to 60hz when non-gaming
and personally i cannot stand the horrible black levels on the TN's as well as the weaker 
color accuracy..ect
 
 And i doubt i'd go with 4K until 2017, as i cannot see the top Nvidia card reaching 4K/40+ for
next year and the graphic engines will demand more processing power as well. 
 
 Add to it win 8.1 scaling is not the best at 4K and even going into Origin's UI, the text is
so tiny in 4K[<--dsr).
 
 I wish i could have waited one more year, but i needed to upgrade from 1080p and from a TN
panel..asap, and using a Titan-X at 1080p is overkill on the gpu side.
 
 So while 4K is really teasing, a 1440p IPS panel is an ideal match with one Titan-X, imho. 
 
 Now hopefully the panel i get is not a lemon..lol
 
 Thanks again guys :)

Excellent decision I agree. Fingers crossed that you get a good unit. Hopefully my replacement will be good as well.

I went with the ASUS PG278Q ROG Swift for a 1440p @144hz monitor and have absolutely loved it since.  They had some QA issues at first but it seems things have leveled out.  Huge difference from 1080p gaming.  I'm powering it with two 780 Hydros while waiting for EVGA to get more 980 TI Hydros in stock.

I love my ROG Swift.  I had my doubts at first, impressive build but terrible panel.  I admit I was spoiled from my Yamakasi 30" 1600p AH-IPS' colour depth.  Also the viewing angles on the ROG Swift are pretty damn awful.  The thing is - from what I hear this is pretty much the best of the best when it comes to TN panels....
 
I still have some issues with the monitor - occasionally the pixels will split or shift creating a double vision type effect - possible SLI related?  I also experience some noticeable backlight strobing on certain images.  Also the other day the monitor would not power on or recognise inputs from my PC or laptop but power cycling from mains seemed to sort it.  I just wish the ROG Swift had that IPS colour depth.
 
This is getting off-topic, but have there been any developments on the ROG Swift replacement rumored to be 4K IPS 60Hz panel?  If they could bump that to 120 it'd be ideal.
 
G-Sync is freaking amazing by the way.  I didn't notice it a great deal, but once I tried a v-sync monitor after being used to g-sync the difference is night and day.

Agreed, don't make the 4k mistake. When you are gaming @ 60 fps only, something you could do back in 1995 on a CRT, you will know,  wow i screwed up. 1440p lets you have 144 hz screen which is the most fluid and amazing thing i have used, since my old CRT i used to use. Also 1440p, especially with the advent of DSR will look just as good as 4k.

Your CRT in 1995 had 4k resolution? 4k DSR does not look as good as 4k native don't be so hyperbolic!

Plus it's harder to do 144fps on high settings than it is to get 60 at 4k. I doubt Witcher 3 stays at above 100 let alone 144!

Solid decision, I think you really enjoy the 1440p 144Hz G-Sync monitor.
I just recently made the jump from 1080p to the ROG Swift monitor and I must admit that it's amazing.
My 1080p monitor was an ASUS 144Hz unit, so I've been spoiled playing FPS games at higher refresh rates for some time now.
 
Post back and let us know how you like it.

 
Thanks. I'm hoping the jump from 1080p to 1440p is impressive, as the only idea i can tell now is using DSR.
 
Why did you opt for the ROG Swift over the Acer? Was it because it can do 3D or the slightly better response time(1ms compared to 4ms)?
 
I was tempted to go with the ROG but i did'nt want another TN panel and i use VR alot and never use 3D anymore, so the decision to go with the IPS panel was easier.
 
But still it's splitting hairs..lol, both monitors are really good it seems.
 
I'll post back when i receive it on my thoughts about it and the jump from 1080-->1440p.
 
Still..i'm trying to get the thought 4K out of my mind..lol. I need a constantly smooth gameplay
and i cannot get that with a single Titan-X. So i hope 1440p will impress me enough to not care of 4K for at least another year.
 
Thanks again!
 
 

Actually the ROG Swift was an impulse buy. Bought it very slight used from a fellow EVGA forum member.
I was toying with the idea of moving to a 1440p monitor but hadn't really looked around all that much.
I'm glad I made the jump, it's been outstanding so far.

Yeah, I'm strongly considering the jump to 1440p myself, but I wonder if any 1440p G-Sync models that have been tested to match or come close to the XL2420G as far as input lag is concerned.
 
DisplayLag has it as the only G-Sync variant tested, though at 1080p. And at a very competitive number of 10ms input + 1ms display you'd expect.
