I own this exact screen. It's okay gaming wise. It goes up to 70 Hz, official Freesync range is 48-70 Hz, I expanded it through CRU to ~34-70 Hz. Contrast is good, colours are nice. Input lag is not the lowest, around 25 ms according to prad.de. I would recommend Overdrive setting +1, because +2 results in visible overshoot.
