Strobelight - LightBoost Utility for AMD/ATI and NVIDIA

[t0b1as]

I've been reading arround about 120hz and 144hz and what the best is for playing games like Battlefield 4.
Now I'm a bit confused about a few things.

I see people saying that you can't use the Lightboost with 144Hz, yet when I look at the opening post of this thread I see a few 144Hz monitors listed?
If this is true, what would be better to get? A 120Hz+lightboost or a 144Hz monitor?

I play Battlefield 4 a lot and soon I'll be a competitive player and im still playing on a 60Hz screen and I'm looking to update to a new monitor.

Tobias
