Summary: I have an older i7 motherboard and this was the fastest graphic card it could support. I had to modify my case to get it installed, but it is well worth it. I finally have the graphics that are excellent for my PC games and my video editing.
Summary: Excellent used buy. This is one of the top 5 single graphics experiences available. Basically 2 GTX 580's downclocked to reduce heat and voltage. Got mine with Koolance waterblock preinstalled and couldn't be happier.
Summary: This is a excellent high performance graphics card. This is 2 - GTX580 gpu's on a single card. They are down-clocked to lower heat and voltage, making it a great solution if you do not want to upgrade to a higher wattage psu and second video card.
Summary: I had heard some complaints about this card being noisy and overheating and not doing well on synthetic benchmarks. I am pleased to say that I am very happy with this card as the fan noise is not at all that bad and the temperatures have not been excessive. It also holds its own in benchmarking.
