sorry if there was already a post about this question, but i did look all over and found nothing. But i have a hp pavilion model type 533w. And i've been looking to see if i can buy a graphics card for my computer as an upgrade. But when i go online I dont understand what they mean by all this talk,such as Video, Integrated, PCI express, AGP, and so on. I'm basically a newer person tryin to understand computers and was wondering if anyone could help me find out if i can get "ANY!" graphics card to help me play new aged games because all this new technology. If so my e-mail is email@example.com , would be MUCH APPRECIATED.
