The Gigabyte GS27QC is okay for PC gaming. It has a native 165Hz refresh rate with an overclock to 170Hz, and it has both FreeSync VRR and G-SYNC compatibility to reduce screen tearing. It has low input lag for a responsive feel, but motion is blurry at most refresh rates, and it has smearing. Unfortunately, it has distracting VRR flicker with changing frame rates, particularly in dark scenes. In terms of picture quality, it displays deep blacks thanks to its high contrast ratio, but it lacks a local dimming feature and highlights don't pop in HDR.
