Note to mods: I figured this is best suited here given the target demographic.
HP has come out with a monitor, the Overlord Tempest X, which is an 27" 1440p 120Hz IPS monitor. Yes that's right, an IPS monitor that can exceed 60Hz. And not only that, it comes at a very affordable price (for a panel of this size, speed, and resolution) of $450. However, there's a caveat. It can go up to
120Hz, but you're not actually guaranteed that. It's in the similar vein as those cheap Korean monitors that people can overclock. Even then though, it's been measured (at least one sample) to have an absolute input lag of 24ms, which competes with some of the TN gaming panels.
