Right around a year ago, HyperX (a division of Kingston) released its first gaming mouse, the Pulsefire FPS. While probably a better option than what you'd find in the clearance bin at K-Mart, it wasn't a terribly exciting rodent, featuring a basic design without any significant customization options. Fast forward to today and HyperX's second gaming mouse, the Pulsefire Surge, looks to be a better option.

For its second run at building a gaming mouse, HyperX went with a Pixart 3389 sensor, giving the Pulsefire Surge a native 16,000 DPI to work with. Not every gamer cares about having such a high DPI of course, but for those who do, this is an upgrade over the Pixart 3310 sensor found in the Pulsefire FPS, which has a DPI range of 400 to 3,200 DPI.
