Our Verdict
Gigabyte G27QC
Gigabyte GS27QC
The Gigabyte GS27QC is the newer version of the Gigabyte G27QC, and they have many of the same specs, but there are some differences. The GS27QC is an upgrade in gaming performance as it has an overclock to 170Hz, and it also has better motion handling with less smearing. That said, the GS27QC also downgrades in a few areas, particularly with office performance, as it doesn't have a USB hub like the G27QC, it doesn't get as bright, and it has worse ergonomics.
