In yesteryear 10/100 networks were all the rage but nowadays that kind of throughput just doesn't cut it. Back in the day (you know when your mouse had a ball instead of a light) 1000Mbit technology was expensive. Fortunately, things have changed and even with inflation Gigabit has never been cheaper.
Linkskey has built a NIC that has all the features you've come to expect. Whether you need to eliminate bottlenecks, expand server bandwidth or chat with 46,780 different people at the same time Gigabit is the way to go.
By utilizing existing cat 5(cat 5e suggested) cabling you can expand network throughput by up to 10 times! Copper networks are a cost effective solution for a fraction of the price of fiber optic networks.
