Q: First of all I have no idea about computers. This is the first time I've actually tried to do anything with my computer and it took me a while to understand what a video card was. I'm running on Windows XP. Here are my processor specification. http://compreviews.about.com/od/budgetdesk/gr/DellDimens3000.htm I'm a hardcore gamer and I'll probably be playing COD4. Looking for a card within the price range of under $100.
A: This seems to meet the requirements for COD4: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3422142&CatId=1603 Its also PCI because you dont seem to have a PCI-E slot. Also DO NOT GET the video cards listed by SkitZaY, those are all PCI-E slots, they will not fit in your motherboard. If your still confused this is a PCI-E Slot (you dont have this): http://upload.wikimedia.org/wikipedia/commons/4/45/PCI-Express-Bus.jpg These are PCI Slots (you have these): http://upload.wikimedia.org/wikipedia/commons/c/ca/Pci-slots.jpg
