NVIDIA's GeForce GTX 680 was introduced earlier this year and has since taken the enthusiast market by storm. It offers great performance at significantly reduced power consumption. NVIDIA's dynamic overclocking algorithm works well and provides a nice speed boost for the card.

The KFA² GTX 680 LTD OC is a unique GTX 680 design. It uses a sexy white PCB and a large triple-fan thermal solution. Its output configuration is unique too, using three mini-HDMI outputs and one full-size DisplayPort connector. GPU clock has also been increased, while memory remains at the NVIDIA reference clock frequency.
