can my comp have a graphics card?

Only the monitor plugs into that particular graphics cards, its the same for most PCI and AGP cards.

One thing though, I would definately recommend the 6200 for you. That's pretty much the best you can get for a PCI card and is much faster than the 5200 you were looking at.

dang! as much as these people talk about this graphics card, http://www.newegg.com/Product/Product.asp?Item=N82E16814139166 I think I just might have to go with this one because I'm mostly looking for improvments on games like battlefield 1942, and people say they run battlefield 2 on medium settings! Thanks for the help on that one Akifuddin! So you guys think a rookie (me), can handle installing the card for my computer or do you think I should have a pro do it? Can this card, which is 128mb, handle more than some 256mb cards? And whats all this talk about overclocking......and can I do that safely to this card or computer?

Good luck! Remember to get the latest drivers from nvidia.com

How can u tell if ur computer supports AGP? I have the same computer and was wondering if it had AGP slots also.

You could run one of the various hardware information programs available but your best bets are to either look on the manufacturers site for the specifications of the board or open the box up and have a look inside (and you're going to have to do this if you're intending installing a card as it isn't magically going to teleport through the case). The AGP slot is offset an inch or so to the right of the PCI slots and is normally a different colour (brown is a favorite) with a slightly larger slot.

To find out if you have what type of interface you have (AGP, PCI-E OR only PCI)

download CPUZ http://www.cpuid.com/cpuz.php After that unzip the ALL the files, run CPUZ.exe (click on the one with the little computer chip). Then click <Mainboard> TAB and see what it says for max supported.

Generally, the memory your video card has, the better. It doesn't have to use system memory. But with such a low end computer like you have, a PCI card will run very slow. It's technology that's being phased out. AGP is next in line to get phased out. Most low end computers come with integrated video - that's fine for office work, but terrible for playing games.

you could find out with sveral programs or open it up and look. I went to HP's website and looked up the model for you. The boads in the pavillion 533w
Is an oem version of an asus board which does support AGP unfortuinently to save money hp stripped off the AGP slot on this model so you can't use any AGP cards. here is a link with specs and a diagram.

you can see the holes in the board where the AGP slot should be (ofset above the top PCI slot) but there is no AGP slot there.
