GPU Shark is a simple system information and monitoring tool which provides a detailed report on your GeForce or Radeon-based graphics card.
The program provides all the usual details on your hardware, for instance: graphics card model, GPU, RAM, memory size, BIOS version, installed driver, Bus and Device ID, and more.
GPU Shark also displays and constantly updates information on your card's condition, though: its memory usage, GPU and PCB temperatures, performance states, clock rates, fan speed, GPU usage, and a list of all the currently active 3D applications, amongst other details.
This information is presented in a rather basic way, and that's putting it politely. There are no neat graphics, no indicators or dials: instead you just get a few lines of text. Some of these are coloured, but that's about the only concession here to readability.
Still, GPU Shark is tiny, and portable, and that convenience is more useful than flashy presentation. So if you're looking for a simple way to monitor your GPU temperature, RAM use and other details then this just might deliver what you need.
