Hi, I'm new here, and am not really that knowledgable when it comes to computer specs. Anyways, I own a Compaq CQ5210Y computer (please no jokes ) and I was curious what I could do to increase the graphics for this computer. I believe that all the graphics are currently integrated intot he motherboard, meaning there isn't a graphics card inside of it currently. I took a look inside and discovered that there was a PCI Express port. Now I've done a little reading and saw that the ATI HD55570 is a heavily recommended card. My Power Supply is 250W. Would that particular card cause problems for my computer? Any advice would be most helpful.
