This graphics card replaced my simple also Radeon. I now use 2 monitors with digital DVI - connection. The installation in a standard case was quite difficult, which has the graphics card with the connection of the two hard drives hooked. Both parts had to decline a little bit to make room for the SATA - to create plug. Finally, the installation went well and I was able to take the graphics card in operation. The speed is absolutely great only the two large fans are now clear, even if not annoying audible. My 550W - power supply provides the power hunger of the graphics card and so I can only the buy recommendation for those who can live with a little -rauschen. (By the way: power adapter is included!)
