I am very pleased with Freesync right now. I have tried Call of Duty Advanced Warfare, Shadow or Mordor, Alien Isolation, and Project Cars just to name a few. I couldn't be happier with how my games appear now.
I have an FX 8350 / Asus CVFZ MOBO / Sapphire R9 295x2 GPU / Windows 7 Home 64 / Catalyst Control Center Driver 15.7 and a Benq XL 2730z monitor.
