I got the ROG Swift too and I'm trying to understand something.
Everyone is praising GSync saying they can never go back etc and I feel like they actually mean the 120-144fps because quite honestly, I've spent hours upon hours playing games with VSync or GSync and there is absolutely no difference. At 144hz of course.
Can people here go to NVCP, change Vsync from "Gsync" to "On", load your games, and honestly tell me there is a difference ? There isn't, sorry.
Borderlands, Tomb Raider, Titanfall, BF3, BF4, Shadow of Mordor, Bioshock Infinite, I tried all of them at 144hz and with Vsync or Gsync I cannot see a single difference.
My specs are i7-4770k, GTX780 Classified, MSI Z87-G45 Gaming mobo, Samsung Evo 256GB SSD, 16GB Ram GSkill 2133 and of course the ROG Swift.
