My PC is about 3 years old. I've done some hardware upgrades in the past -- added RAM, new hard drives, and upgraded my video card once. However, I'm a programmer and my strengths lie in software rather than hardware. I don't do a very good job of keeping up with whats going on in the hardware world.

A few months ago, I started shopping around for some new video games -- mostly because it was my birthday and people kept asking me what I wanted. I realized that my ATI Radeon 9600 just didn't cut it anymore. Most of the newer games recommended (if not required) better. So, I also started trying to figure out what would be a good video card upgrade.

Much to my surprise, its hard to find a decent video card for my antiquated AGP slot. Add to that the fact that the ATI and nVidia seem to have changed their naming schemes a few times. I'm finding it difficult to determine which cards are better, are available for AGP, and are worth the price.

I would welcome any suggestions of where to shop and what I could hope for. I'd prefer to keep it under $100.
