Right now im running Cable through my USB port. Speed seems pretty good but anything is better compared to dialup. I do have a brand new Ethernet card (Netgear 32 bit PCI Adapter) which says 10/100Mbps on the box. If I install it what kind of speed boost (if any) can I expect? According to some online tests my speeds are the following. Thanks for the help.

cnet 701Kbps
performance.toast.net/ 871Kbps
http://www.bandwidthplace.com 3.3 megabits per second
