chipset for vista?

the only piece of hardware which will have to adjust itself to the dx10 architecture will be the video card, so you can build your system now, just don't waste your money on a dx9 card, wait for dx10 compatable hardware to come out...or you can just wait it all out together

No, all DirectX 9 video cards can run Windows Vista without Aero (that is, Vista Basic), and most new DirectX 9 video cards will run the full Aero Premium interface.

According to Vista's system requirements,

to run Aero, the card must have:
"Support for DirectX 9 graphics with a WDDM driver, 128 MB of graphics memory (minimum), Pixel Shader 2.0 and 32 bits per pixel."

DirectX 10 cards will run both DirectX 9 and DirectX 10 games, but DirectX 9 cards will only run DirectX 9 games.

The first DirectX 10 cards are coming out next week, and will be very expensive, and, I suspect, will have very high power and case cooling requirements.

Fuzzy

I'd bet they'll be a crack or download or patch to enable DX 9 hardware to run DX 10 games, unless the hardware just can't support it???
