Hubby has a 144hz TN monitor with freesync and it is lovely and smooth! I have a Dell IPS 60hz, better colours but lower response time, I have not found that it has hindered my gaming in any way though. The 144hz is lovely, I am jealous! Down the line I will upgrade to a 144hz but would pick an IPS panel - graphic artist as well as a gamer. When I bought my Dell I don't think high refresh rate IPS's were in my price range.
