The SAPPHIRE HD 6670 ULTIMATE Edition delivers new gaming experiences and acceleration of next generation high performance applications yet runs totally silently. All of this comes with low active power consumption and Dynamic Power Management delivering super low-power operation in 2D or idle. As the core technology is low power, no external power connection is required, making this series ideal for system upgrades or mainstream PCs that do not have high end power supplies.
It is quiet, it is short it plays 1080p well in bluray or streaming. This was the first card in the first ht I built for a friend. It is a bit old school but the length can help it fit in a short case. If you have a longer space the hd7750 is the better choice. fanless and has more power to process then this one.
