Cooltechzone claims NVIDIA will not launch an AGP version of the new GeForce 7800 GTX card. AGP will soon fade away and thus it's also unlikely that ATI will launch new AGP video cards.
An insider today confirmed that NVIDIA has no plans to offer an AGP version of the 7800 GTX currently, but it all depends on the demand. The reason is not because the 7800 GTX couldn’t be ported over to the AGP standard architecturally, but NVIDIA just doesn’t see the demand anymore. But if users are persuading enough, NVIDIA and its board partners would have no problems offering an AGP counterpart to the PCIe version.
This might also mean that ATI won't launch an AGP version of its upcoming R520.
