Summary: ZOTAC's GeForce GTX 580 AMP! Edition does not bring many improvements to the table. The card is a complete implementation of NVIDIA's reference design with higher clocks. Its increased clock speed of 815 MHz, vs. 772 MHz on the reference design, can deliver a small performance improvement in our benchmarks - up around 3%. If you are willing to do some additional overclocking then you can expect a higher clock headroom on the AMP!
Pros: Fast!, Overclocked out of the box, Quieter than other cards in this performance class, Better overclocking potential than reference design, Reduced power consumption, CHiL voltage regulator with I2C voltage control support, Native HDMI output, Prince of Persia full game included, Support for DirectX 11, Support for CUDA / PhysX
Cons: High price, Uses reference design cooler, Still not as power efficient as AMD's designs, Power draw limiter could complicate advanced overclocking, Still limited to two active display outputs per card, DirectX 11 relevance limited at this time
