Hello, I have recently decided to get a new graphics card for my HP Compaq Presario CQ5320Y. After opening it up I only see one PCI slot and 2 black slots that are unkown to me. I have done a little research and some sites say that there are PCI express slots but i am not sure which ones those are. Anyways after looking around, I decided on this card but am still not sure if its the best i should get, an suggestions? I am looking for a card for mostly gaming and am willing to spend up to $100 - $150 tops. This is the one I have decided on so far. Galaxy Technology 512 MB DDR3 GeForce GTS250 Graphics Card 25SFF6HX1RUI (sorry about no links unable to post links or images for now)
