I have seen this kind of activity when using onboard ethernet. This is usually do to the fact that the onboard ethernet is cheap. Giga-byte is an inexpensive ethernet card, while it will work it will not guarantee you good speeds. I personally like 3com cards. You also mention download speeds, if you are talking to a web site, there is a possibility that it is the cause of the slowdown or something between your machine and the web site. Unless your ISP provides 1G speed (most do not) you are only looking at 10Mb. You have to remember that the speed of any ethernet card is what the card can handle with a continuous steam of data with no errors. Since under most cases this is not the case, even with lets say 10Mb at best you will only get 6-7Mb/sec (if you are lucky). The best way to test your card is to have two machines on the same lan and try transferring between the two machines and calculate the speed that way.
