Dont know what graphics card I can put in my PC.

1998? Does that thing even have an AGP port? We would need to know more about your motherboard to suggest any possible upgrades but most likely you really shouldn't bother on such an ancient system. You could find a better computer on ebay or craigslist or in a thrift store for less than $50.

Yeah, agree with jyjjy above, your machine is just too OLD, upgrading it will cost more than buying used computer which is better than 1998 pc...

Your only option is a PCI card. Not the newer PCI-e card.

Here's a list that's available at Newegg.com. Good luck.

Forget upgrading a 12 year old computer and get a new PC.

what I want to know is how does a 1998 Pc detect a 500gig Hdd, isnt there like a 80gig detection limit on that bios?

Yah somethin like that. To all of you thanks and I do have a modern PC (Asus board/Sparkle vid card..)The HDD is an external, and my internal is 40gb. I just need somethin with S-Vid to hook up to my flat screen. If you guys saw this computer you would know why I want to put somethin in it, yah know.. (Full custom case) Thanks <<iG3n>>

You can put new parts in the case I would think. Replacing almost everything else can be done for less than $200.
Anyway we would still need to know more about the motherboard to make any suggestions.
