...you remove the cover and plug in the card into the PCIe x16 slot, which presumably your computer has. I would hope this card comes with an installation booklet, but two things you'll need to do are to disable any built-in graphics on your mobo or CPU and install the driver that comes with the card.
I just bought a Geforce 8600GT graphics card so that I can play some games, as my current graphics card was too bad to support the games I wanted to play, and someone recommended the 8600GT to me as a graphics card.
Can somebody please tell me how to connect graphic card to my PC ? And whether or not I will need to get some other things to connect it, like a cable or something ?
