yes.......
And you have to disable the integrated graphics card.
To disable your integrated gpu (graphics card unit), you will have to enter your BIOS, directions are on the screen at first when you start your machine (often del or F2).
There you will have to search until you find a setting like "onboard graphics: Enabled" and change it to "Disabled".
But don't do this before you install your new card.
.. Lastly, if you feel uneasy about doing the upgrade yourself, you can turn the computer into a local computershop and ask them to do it for you.
But don't pay them too much for doing it!
Check on your computers site and see if you can do the upgrade.
