Having successfully launched their first 28nm GPU last January, AMD went on to release an entire family of Radeon HD 7000 GPUs over the next few months. The last of the series were the Radeon HD 7870 and 7850 graphics cards, which were closely followed by the launch of Nvidia's next generation flagship part, the GeForce GTX 680.

Fast forward to the present day and it'd appear that AMD is desperate to claim the bragging rights of offering the single fastest GPU money can buy. As the name suggests the Radeon HD 7970 GHz Edition features a core clock speed of 1GHz, along with overclocked GDDR5 memory running at 1500MHz. AMD plans to charge a small premium for the GHz cards at $499, but is it worth it?
