High frequency monitors - worth or not?

[Mate de Vita]

Cross-posting a part of this question because it fits better in this forum.

I'm building a computer for the first time, which will be used for 3D design applications (Unity3D, 3DSMax, Maya, etc.), programming, free-time entertainment (gaming, movies, etc.), and possibly some hobby Photoshop work (nothing professional). I have a roughly 1000-1500€ build with a GTX 1070 ready, excluding the monitor.

Having never used one, how much of a difference do 144Hz (or other high frequency) monitors make? I've always used a 60Hz (or lower) one up till now and never found it inadequate for movies or games. The 144Hz mark easily adds 100-150€ to the price of a monitor (which is already the most expensive part, given that I'd like a QHD 27'', which start at 400+€ for the 60Hz versions). Is it really worth the extra 150€ for the 144Hz and possibly another 200€ for the GSync (since FreeSync doesn't work with NVIDIA cards, no?) or will a no-GSync 60Hz do just fine?

once you game using more than 60hz screen (100hz , 144hz , 160hz) you will never look back. but this is only for gaming. If you want design and color then go for professional Screen with billions of colors support and wide color gamut and more resolution...

as for Gsync , they are good , but at a price , but the more fps you get the less you will notice tearing and stuttering.
