Re: Help me choose next monitor: 144hz 1080, 2k or 4k?
Running on a single 4k panel, a Titan X will just about manage static 60 frames per second at high settings in SOME lesser and medium demanding games. For example, in BF4 you'd see static 60 at 4k (usually) whereas you'd be seeing 30-40fps on Crysis 3 (high settings)
Two 980Tis in SLI will do a similar job to a single Titan X. a 970 is a single-panel 1440p-oritned card IMHO. Match your FPS to the refresh rate of your monitor, if you can only push 60 FPS, you only need 60Hz. If you can push 75 or 144 FPS in your favorite games, go for 75Hz or 144Hz respectively.
No point getting a 144Hz panel if you have to turn all the settings down to match the frame rate to the refresh rate... not least because you'll see significant screen tearing on a TN panel if its refreshing 144 times a second but you're only rendering 60 frames.
This is how I rate/how I think of Nvidia's lineup of GPUs (High/Ultra settings with 2xMSAA):-
GTX950 - 720p, 1080p
GTX960 - 1080p
GTX970 - 1080p, 1440p
GTX980 - 1440p
GTX980Ti - 1440p (4k with 2 or more in SLI)
GTX Titan X - 1440p, 4k
If you're not planning on gaming, every card in Nvidia's 900 series will output in 4k and run the desktop and movies no problem. Bare in mind there is NO POINT buying a monitor with a higher refresh rate than 60Hz if all you plan to do on it is watch videos or movies. 99% of all video content is only shot in 24/30FPS, so you'll see precisely zero difference. The most frames per second you'll see in a video is probably thw 1-2% of YouTube videos that are uploaded in 60FPS.
