The older 28" 3840x2160 models (the Philips and Samsung there; note that Dell, Asus, and many other companies have their own similar models too) use TN panels.

If this is for gaming, don't underestimate the graphics card requirements to be able to play in higher resolutions. 2560x1440 has 178% of the pixels of 1920x1080. 3840x2160 has 400% of the pixels of 1920x1080. The difference up to 3840x2160 is huge. And some games don't quite scale UI elements well for higher resolutions.

Outside of games, text scaling still is a problem in many applications.

The IPS monitors have some issues with IPS glow (some models less so than others, but the U2715H isn't among the best), which may make them less good for a game with a lot of dark scenes, for example. Keep in mind that with the larger screen sizes, the more you'll see things off angle and see these things. But overall both Dell monitors should be good. Reviews of the P2715Q seem relatively scarce, though. And keep in mind that there are a lot of 2560x1440 IPS monitors, and some may be functionally equivalent or slightly better. But if Dell is what is readily available, that should be fine.

For alternatives, check the review sites like prad.de, tftcentral, etc. Actually, for the 2560x1440 models, this thread may help:

120-144hz can be either the most important part of your system or pretty much worthless to you, depending on perception. Also those higher resolutions are still quite demanding

If you're trying to run at the resolution of your monitor and FPS at refresh rate (or say, refresh rate *1.2 etc of each monitor, it doesn't change anything here)

1080p60 = 100% cpu and gpu requirement

1440p60 = 100% cpu requirement, 178% GPU requirement

4k60 = 100% cpu requirement, 400% GPU requirement

1080p144 = 240% cpu requirement, 240% gpu requirement. This is where you hit those stone walls of "hang on a second, everyone else said my CPU was good!" - they might be getting FPS of 2/3'rds of their refresh rate at 40fps in dips, but that's only ~28% of your refresh rate. Those drops from 160 to 100-120fps, while miles above the heads of most gamers, is something that you will notice and experience extremely often. And those games like Wildstar and Grey Goo that dip to 30fps or even less, well, it kinda ruins the point of having a fast system if the game just can't keep up with any CPU available on the planet. With a huge list of games available that perform awesomely, it's harder and harder to even pay any attention to those badly performing games, even if they're excellent games.

at 4k for example on a single 980 you'll have to turn down settings a lot on demanding games.

I have a video of SOM on an OC'd 980~

that's FPS with pretty much everything or literally everything minimum aside from Textures medium. If you raise other settings, FPS would drop a lot (but you can't raise textures to high or ultra, you have to leave them at like 1/4 of the max resolution because of VRAM constraints)

Overall if you're getting 4k i would strongly recommend one of the gsync 60hz monitors, but 1080p-1440p is much easier to run. Generally 1080p and 1440p are pretty much the same pixel density so they both require the same amount of AA etc, 1440p screens are just bigger. 4k is usually ~1.5x the pixel density.

That PPI change (pixels per inch) is what many games and applications don't handle well; they assume that your screen will just get bigger and bigger as resolution increases. While a 1440p screen has ~78% more pixels than 1080p and is usually around 70% bigger, a 4k screen has 300% more pixels than 1080p and it's not usually 300% larger. Even if it was, UI elements would then be waaay over in the corners of your screen and you wouldn't be able to see them well, so scaling a lot of the time is an issue. Developers just need to make UI elements bigger.

Blizzard does it quite well, their games being played at 4k will automatically double the height and width of everything in the UI, so that it takes up the same percentage of your screen, but many application and games developers have just made the wrong assumption that every screen is ~100ppi or close to it (that was kinda the case in the 90's to early 2k's) and have not caught up yet
