Those numbers do seem a little low for broadband especially the download. Incedently you can think about the gigabit card like this. If you download speed is 650 Kbps and your current card is 10/100 Mbps then you current card is about 154 times as fast as your internet connection (650 Kilobits divided into 100 MegaBits). You would literally need a 100 Mbps connection to use the speed up you card. So I don't think a gigabit card will do you any good for surfing the internet.
