What is the best way for me to achieve the most lagless and smoothest gameplay my build can handle with a GTX 1080, i6700, and a 1440p 144hz monitor. I usually play commercial games like Watch dogs and Witcher 3.

I know that v-sync causes input lag and I kind of wanted to avoid that as I'm not even sure how bad it will be with a wireless controller, and I read somewhere that a frame limiter by itself could do the job? I know I wont achieve perfection without something like g-sync, but what are your thoughts on the best measures I should take?

Well, relatively smooth yes. Screen tearing can and will happen without a sync technology because the monitor can't perfectly sync up with the frames given to it by the GPU, so if the frame changes in the middle of a refresh then you'll still get a torn frame. This becomes more apparent with 144Hz panels because you have more refreshes, so it's much more likely to happen, and it also happens when you have massive framerates compared to your refresh rate because when you're rendering more frames it's easier for a new frame to be received mid-refresh.

Frame rate limiters, rather than forcing the GPU to wait for the next monitor refresh, will just force it to output up to a certain number of frames. It's like V-sync, except it doesn't add...

G-sync gives you the best of both worlds, but has that well known 100$ Nvidia tax. If you're not willing to pay extra for it, then you can use either V-sync in games not very latency-sensitive to eliminate screen tearing and use framerate limiters in other games to reduce screen tearing.

There is also no known universal way to eliminate stutters aside from using G-Sync (or Freesync for AMD). Personally I say that even with that 100$ extra G-sync is worth it, but it's your money.
