A friend of mine asks if there are specific gaming monitors that are better for MMO than others? I don't think there are, just for fast-paced FPS games, you would get a 144Hz monitor, but for MMO games, I'm not so sure. I think it needs either FreeSync or G-SYNC, since it eliminates screen tearing and that happens at all refresh rates.
I've looked here: best gaming monitor and I believe the AOC G2460PF will do the job for a budget gaming monitor. What do you think is the top gaming monitor for this purpose?
