Intel Pro PCI 1000t 10/100/1000 1 gigabit Ethernet card - $10 (St Petersburg)
I have 2 Intel Pro 1000t 10/100/100 1gb PCI Ethernet cards all in perfect working order. Great for upgrading your slow 100mb network card or adding a second NIC to your system. These are the best and fastest 1gb cards. They work on any operating system.
