Ah, so I'm guessing you don't have an adaptive sync (G-Sync or FreeSync) display. You can of course still run Fast Sync in some games if your hardware is up to the task (and NVIDIA-based). Most pro gamers playing Overwatch/CSGO/MOBA will go with a plain 144 Hz since they run Fast Sync or similar. With G-Sync you want V-Sync always enabled in CP (never in games) because it "fixes" upper frametime variances (roughly 120+ at 144 Hz) without any latency hit. Blur Busters is a good source for general information for those looking to buy such a display.
Mind you, simply having a 144 Hz display reduces your latency significantly over 60 Hz, but with V-Sync to prevent tearing you usually run triple buffering which adds several frames of input latency. So if you think 144 Hz with V-Sync is smooth, wait until you try G-Sync/FreeSync. Although again you can have issues at the FPS cap but...yeah. I just think a lot of people are confused about how all the technologies work and you often hear people saying 144 Hz isn't much better when 9 times out of 10 they have it set wrong and it can make a HUGE difference.
I'm glad the price is coming down on VR but I'm still in a wait phase on it. My friend did have a Vive we played around with for a project (VR real estate, long story, Vuze was also involved) but yeah it's not there yet for me.
