One of the best Black Friday/Cyber Monday deals we've come across this past week is for the Acer Predator XB271HU. It was originally priced at $700 and usually goes for around $600, but now you can get it on Amazon for $550.

This is a 27-inch 2560 x 1440p IPS monitor, with 144Hz G-Sync support (overclockable to 165Hz). It also has minimal bezels around the screen and 2 x 2W integrated speakers. For ports, you get one HDMI 1.4, one DisplayPort, and four USB 3.0.
