I'm kind of surprised that video card is able to run the game at all.

Are you sure that you actually have a connection problem? Your Send/Receive will turn yellow/orange/red if you're having connection issues. Don't pay too much attention to the numbers.

More than likely you're playing with a really low FPS. Please provide more detailed information on the problem you are experiencing.. and turn down all of your settings in the FFXIV config utility.
