ECS brought a dual-system with AGP and PCIE already for Socket 755. But that was a bad only good for users who might be able to live with a "weakened" AGP port for a limited period of time. The manufacturer decided to provide an AGP-compatible slot based on PCI, by merging the voltage feeds of two slots into the AGP connector. This slot, dubbed AGP Express, is not an enhancement to AGP in any way, but rather a PCI slot physically adapted to look like AGP. SO if there will be AGP for Nforce 4 it will be something very similiar, which means something crappy if u are a gamer. If ur a gamer the low performance numbers wont please you. If ur looking for cheap upgrade and keeping ur agp card its worth a look. But i dont know a nforce4 board with AGP...
