Summary: If you're looking to add gigabit connectivity to a legacy PC this is a great way to go. Inexpensive and well made. I've been running 4 of these for a few years now. As easy to install as any other card. It works well.
Solid performance for traditional use...be careful for exotic uses.

Summary: Inexpensive and solid performance. Recognized by most OSes for traditional use...some challenges when binding multiple NIC cards together under FreeNAS to increase bandwidth (works fine splitting across multiple subnets, providing fall-back NIC support, etc).
Summary: I've used these cards extensively on many of my pc's. At some point in time the mobo netwrk port will fail. You might as well buy one of these and be ready or just go on and use it when you get it.
Summary: Blessed with a computer savvy friend. But I did this myself and it worked great. Just wish jargon/terminology acronym use was easier to translate when shopping for computer parts. Told by my internet provider I needed a NIC card or NEC card. Anyhooo all's well that ends well.
