Thank you! Now how do I determine which kind to buy...I mean...I heard that you have to check whether you have PCI or AGP....how do I check to see which one I need to get? Thank you very much for responding!
There's no way to be certain if your PC has an AGP slot for AGP display cards other than to open the case and look. Motherboards can have an AGP bus without having an aAGP slot, if the onboard video uses AGP. The AGP slot is set back further than PCI slots, as shown here.
If your motherboard actually has one, download and use Everest Home Edition and/or CPU-Z and let us know what make and model your motherboard is reported as. We'll be able to tell you what sort of AGP card would be suitable to use. Some older motherboards are not suited to modern AGP cards, and require older ones.
I have an HP.....Windows XP.....trying to play Leisure Suit Larry the new one and get a box pop up that says: Your video card appears to lack hardware transform and lighting support. The game is unlikely to run correctly. Do you wish to continue? I did continue and let's me play the game but it's choppy and looks like a scrambled channel you get on your tv for pay per view when you don't pay for it. lol...anyhow....I figure I better go ahead and get a new one if I continue to buy the new games. My computer is only about a year old...it has Intel (R) 82865G Graphics Controller. Does this help you?
You should be looking at an NVidia based 6600GT card at minimum if 3D games are the object of the exercise. Although you can purchase cheaper, they provide really good performance at an affordable price. Anything less will disappoint you in the longer term ;)
BTW, Catweazle said to look for a 6600GT minimum. So if you want another one that is a bit better it is also good. It just depends on your budget.
Nvidia: 6600gt, any 6800 card
ATI: any x800 or x850 card
128MB is enough for most games today. If you dont plan to upgrade or change computer too soon, 256MB would be good for upcoming games. Today only DOOM 3 can really take advantage of the extra memory (needs 512mb for graphics at ultra high).
