Introduction
Zotac is a new player in the video card business. They are manufacturing only NVIDIA video cards and were established earlier this year. However, they have great potential because they are affiliated with PC Partner who supply cards to Sapphire for example too.
Their GeForce 8800 GTX OC is, as the name suggests, an overclocked version of the GeForce 8800 GTX. All specs remain the same, except for the clock speeds which were raised by Zotac to 630 MHz core and 1000 MHz memory. The core clock is even higher than that of the GeForce 8800 Ultra which was released just a few days ago.
