Intel's upcoming G35 IGP chipset will feature DirectX 10 support and it will be released in the third quarter of this year.
The Intel G35 supports the company's upcoming dual-core and quad-core 45nm processors, including Yorkfield and Wolfdale.
It supports FSB 1333 and DDR 2 800 only. If you want DDR 3 support, you will have to buy the G33 but this one won't have a DirectX 10 support.
The G35 chipset also supports Intel Clear Video architecture. You can use it together with ICH8, ICH8R or ICH8DH. Intel also says that something called SW POR is under investigation. This has something to do with software portability at a guess.
