As if to prove that AGP isn’t quite dead yet. Powercolor has quietly released a new Radeon HD4770 card that’s AGP compatible.  From ExPreview:

Based on 40nm manufacturing process, PowerColor AGP HD 4770 features core/memory clock of 750/800MHz (DDR 3200MHz), and supports ATI CrossFireX. Since ATI Radeon HD 4770 chip doesn’t feature native AGP support and Powercolor uses a special bridge chip to enable support of AGP interface, end-users have to ensure that the card is actually compatible with their motherboards and systems.

The Radeon 4770 is the first 40nm card, and has been burning up benchmarks all across the net.  Whether or not the same performance is visible on AGP is unknown, but I’ld have to believe that the slower bus speed would cripple it significantly.
