Updated: | By The Competitive Gaming Team

If you want to dominate in FPS games or build a setup that turns heads on Twitch, your peripherals matter just as much as your graphics card (though you'll also want to upgrade to a Wi-Fi 6E mesh router for a stable connection). Here is our breakdown of the three upgrades that will actually improve your aim, reaction time, and visual experience.

3. The Reaction Speed Advantage

ATTACK SHARK X68 HE Rapid Trigger Keyboard

The Verdict: The best budget entry into Hall Effect / Rapid Trigger technology.

  • Specs: 60% Layout, Hall Effect Magnetic Switches, 8KHz Polling
  • Why we love it: You don't need to spend $200+ to get Rapid Trigger. The Attack Shark X68 gives you adjustable actuation points, meaning your character stops moving the exact millisecond you let go of the key. It's a massive advantage in tactical shooters like Valorant or CS2.
