Hi, I work for Intel. Here is some clarification: The importance of DirectX 10 is that it becomes a Microsoft Premium Logo requirement for all systems WHQL’d after June 1st 2008. Intel is not claiming this driver is a suitable solution for playing available DirectX 10 games. Right now, a discrete card would be required if DX10 gaming is your desire.
Also, DX10 is only supported by the Intel® G35, Intel® GM965, GL960 Express Chipset products as well as future products. It is also probably fair to point out that according to recent reviews, no DX10 capable integrated graphics are suitable for DX10 gaming.
Also, Intel's intergrated graphics chipsets excel in video playback. In standard definition some enjoy HQV scores of over 100. the Intel G965 and up are capable of playing HD content (eg: Blu-Ray). My Blu-Ray/HD-DVD media centre at home is based on G965 and it runs beautifully. The upcoming G45 has dedicated HD hardware in it that allows it to decode the top three HD codecs while using only small amounts of power. Everything depends on what you want to do with your integrated chipset.
