I've got a Dell Oplex 960 with a intergrated graphics card on the motherboard, I know nothing about computer hardware. Can somebody tell me how to swap out my graphics card without losing all my data? my case comes with a case key if that matters. Here are my specs and the card I'm going to put in. My pc is fast, it just needs a upgrade to it's graphics card now.
I've never opened a desktop case before exept to dust my PC every year, I do not know what all the cords go to or what pieces of hardware goes where lol.

Where do I find the videocard slot? and how do I hook it up? Can someone help me with that? do I have to unplug the intergrated graphics card from the VGA slot my monitor hooks up to?
