Im going to be getting a new monitor but im stuck between a Dell SE2717H 27 Inch Full HD, IPS, AMD FreeSync™ which has 6ms response time or a Dell SE2417HG 23.6in Full HD with a 2ms response time but no free sync.
Some would claim a slight 'lag' but those would be the best of the best in competitive FPS gaming.
To the average gamer (heck, even an above average gamer) though, no.
