We wrote about D8M in June and you can read about it here. It is a mainstream card that Nvidia plans to reveal in November. The high end part won't be codenamed G92 and it will be known as D8E where D stands for Desktop, 8 for the eight generation and finally E as an Enthusiast.
D8M and D8V where V stands for Value comes in November while the high end D8E part will be pushed in early 2008.
The cards support Display Port, PCIe 2.0 and DirectX 10.1 and it is the 65 nanometre part.
