I have a 1070i OC'd to a good bit above a stock 1080 and i use a 1440p 144hz monitor and sure i dont get 144hz n max settings, but i get 120 hz max settings on games like pubg, metro redux, fallout 4, and it is gsync and ive never had any issues. highly recommend
I'm not saying theres anything wrong with gsync. Its just not worth the extra money.
It's worth the money if you are determined to buy an NVidia card. It certainly doesn't help you play better in multiplayer games but in single player you can turn everything to max and not worry about tearing and it just feel nicer. Now it's not better than Freesync but you need an AMD card to use Freesync.
If GPUs weren't in stupid mode right now (literally couldn't get a 1070 today if I was willing to pay $1000 or a Vega for $1500) I's say yah, buy AMD and Freesync. If you don't need adaptive sync at all pick up somehtign with 144hz and it'll work fine with either. There's only a $50 price premium on Freesync over no0sync so you don;t take much hit useing Freesync with NVidia cards either.
As a side note: 2K is 1080p (roughly. technically 2048*1080 according to Digital Cinema spec). 1440p or QHD is actually 2.5K (2560*1440) and almost double the pixel count of 2K. The whole idea of using one number (the horizontal pixel count) is silly and lazy since we have multiple aspect rations out there and we really should always state computer graphic resolutions in both dimensions in my opinion. That said if you actually mean 1080p you are in total overkill mode with even a 1070ti, I run a 165hz 1440p Gsync screen with a 1070 just fine; I prefer lower settings in multiplayer games anyways so I get 120+ and in single player 80FPS is good enough so I can crank the settings for immersion.
Both the monitors you put forward are 2560*1440 (2.5K if you have to use "K" as a measure). I Would buy the 144Hz one over the other for gaming without question regardless of GPU. Your monitor should last 5 years or more...buy a good one. You might buy a new GPU in 6 months.
