The AGP motherboard expansion slot standard is used in older computers. Newer computers come with PCI Express slots instead. Because of this, video card manufacturers target the latest graphics cards at PCI Express motherboards. Luckily, you can still buy AGP video cards. If you're looking for the best gaming video card for your AGP-supporting motherboard, there are a few good options.

EVGA GeForce 6200
The EVGA GeForce 6200 isn't as powerful as the above-mentioned ATI cards, but if you prefer NVIDIA cards and want a cheaper option, it's also a great choice. Unlike the ATI cards mentioned above, the EVGA doesn't have a fan, it's passively cooled, which means that this video card will be quieter and there's no risk of the fan mechanically failing. This video card also only requires a 300 watt power supply, whereas the above ATI cards both require a 400 watt power supply.
The EVGA GeForce 6200 has a core clock speed of 300MHz and two pixel pipelines, and includes half a gigabyte of GDDR2 graphics memory with a 64-bit interface and a 532MHz memory clock.
Unlike the above ATI cards, the EVGA only supports DirectX 9. It also comes with DVI, D-Sub, and HDTV / S-Video out connectors.
