1080P vs 1440P 34" Ultrawide

[xander25]

On my screen right now I have two separate tabs.

One has the LG 34UM95 for $999
The other has the LG 34UM65 for $679

I've done my research and I'm sold on 34" widescreen gaming. The difference between these two monitors is that the 34UM95 is 1440P and the 34UM65 is 1080P.

I have a GTX 780ti so I believe I can handle the 34" 1440P

The question is how impactful is 1440P in gaming? I have a 1080P right now and haven't used a 1440P yet. My game preferences run towards things like Dragon Age, Shadows of Mordor, Bioshock, etc.

Thank you in advance for your advice!

Edit for Clarity:
It's not a question of whether my card can run it. The advice I'm seeking is whether the picture difference justifies the expense. I know this is highly subjective, but no one whose house I can simply go to and see has a 1440p monitor so I'm seeking the opinion of the experts here

A 1440p screen has 70% more pixels compared to 1080p.

It depend on your other hardware.
But you should be ok with a 1440p gaming. Look up benchmarks of the GTX 780Ti, there is usually a 1440p or 1600p.

I use an IPS 27" 1080p monitor beside an IPS 27" 1440p monitor and i game on them both, for instance if i am getting lower frames than i would like in 1440p i will switch to the 1080p monitor. The only difference i see between the two is that the 1440p has an amazingly lower amount of jagged edges which increases detail in small or far away objects, and this is coming from a person that never uses anti-aliasing, the blur makes me strain my eyes. So i would only say get it for gaming for sharper image quality without anti-aliasing, if you do use anti-aliasing it really does not look any different from 1080p.

That being said, at 34" 1080p looks really blocky up close, i had a 32" 1080p tv i used to use as a monitor and sitting about 2-3 feet away made games look abysmal, almost downright unplayable. So unless you plan to sit far away from that 34" 1080p monitor it isn't a good buy for gaming.

Another thing to note is running at 1440p with no anti-aliasing gives better performance than 1080p with x4 msaa "at least in my humble opinion and 2 years of experience with messing with the two settings" and is a lot sharper.

And if my r9 290 gives me about 60fps at 1440p in about every game i play with a bit of tweaking, some games i don't have to tweak, Shadows of Mordor runs 50-65 in 1440p on ultra, a 780ti should do just fine with the extra pixels the ultra-wide has. As for being ultra-wide i haven't used one before but I actually plan to buy that new lg curved one as well, and unless you are restricted by a budget $700 is insane to spent on a 1080p monitor even an ultra-wide one, go buy 2 1440p korean monitors for $300 each if that is the case, it will be a much better value.
