From the review: Page 15 - NVIDIA has a winner on its hands in the AGP arena. The GeForce 7800GS can clearly push out high frames rates with ease despite the limitations of the AGP 3.0 specification. It could handle everything we threw at it. The GeForce 7800GS definitely has serious horsepower and easily beats anything previous AGP offering from NVIDIA.
