Questions about updating your video card?

I have a ATI Radeon X1600 Pro with 512MB 8xAGP. I want to upgrade my card, but I am not sure which one I need to buy. I tried looking online for cards with the same specifications, but there are many manufacturers and all with different prices. I was also wondering if anyone could tell me about the HD graphics cards, are they better than the one I currently have? I am looking at the price range of 100-200 dollars. I don't really care if the card has any crossfire capabilities, but I am interested in cards that have Direct X10 capabilities.

Thanks.

That card is 3 generations behind of current gen gpu's.

Going to a HD4670 or a geforce 9600gt will be a huge upgrade in performance, but you have an AGP system so that means upgrading the motherboard and even probably suffering a huge bottleneck on performance because of the other components.
