Often confused.All the G sync compatible options are on the newer WOLED panel which has the 800R curve. G sync compatible isn't really neccessary these days though, most monitors are Freesync and will work fine with Nvidia, AMD or Intel GPUs.
For purely gaming I wouldn't look past the classic Alienware, if you're mixing some other use in there you can look at newer panels which have improved text clarity, and example being this Gigabyte that I am currently using myself.
