MSI Afterburner
Whether you game, mine, or both… MSI’s Afterburner is the best overclocking tool you’ll find for your GPU. It works perfectly for any brand card, and applied your pre-set overclocks on startup, so you only need to set it once(unlike AMD’s Overdrive tool). If you want to get the most out of your GPU(s), this is a must-have.
