This one is actually quite nice because it has a PCI-E 8x interface, useful for weird servers with odd expansion slots. Ran stable with 20 runs of 3dMark Sky Diver. It works good as a display output, and not much else.
Purchased to install in a Dell R710 server running Ubuntu. Easy installation. Auto configuration. Fan noise not noticed to be above server's lowest running fan speed. User experience a great improvement over motherboard graphics system.
