It's an eMachines video card. They made combined video and ethernet cards, on some the ethernet was only available with an optional daughter card, this is one of those cards without the option.
So, just a video card. Should have accelerated graphics. My experience with eMachines cards is that the specs are quite good, they tend to do millions of colours and be accelerated, but the drivers are a little flakey.
If it's cheap, jump on it, if it is... A more than a Radius PrecisionColor XK, get the PrecisionColor instead.
