When installing a new video card, is it necessary to remove my previous integrated video card?

I am looking to install a new video card and I am just wondering if it would be necessary to remove the old integrated video card that came with the system. Here's a link that gives you all the necessary specs on my setup, take a look and tell me what you think. Thanks.

P.S. I've narrowed it down to two video card options for my system, which would be a better buy?

P.P.S. If you know of any better deals or video cards that would be compatible with my system feel free to let me know.|||Integrated means that is is on your motherboard ... in other words its impossible to remove it so no you do not have to remove it your computer should automatically choose the better one.|||You can not physically remove an integrated card. Usually you can just add the new card and it will work. I have heard some people have had to disable or remove the drivers for the integrated. I have never had that problem though.
