Asus ROG Strix XG27AQM-G

This is a 27-inch IPS panel at 2560x1440, refreshing at 270Hz. Response time is rated 0.5ms. High refresh matters most in competitive titles — pair it with a GPU that can actually push 270 fps at 2560x1440. Expect to pay around $369.99, which lands it among high-end options.
