Zotac NITRO Graphics Card Overclocking Controller

Zotac’s NITRO is probably the first external graphics card overclocking controller. Designed with gamers in mind, the device allows you to dynamically overclock your GPU – including engine, shader and graphics memory clock speeds during actual game play.

The 3 buttons on the front of the ZOTAC NITRO allow the clocks to be adjusted up or down to get the frame rates you want with instant results. It uses USB interface.
