The first version of Halo will be released for the Xbox game console by Microsoft. It is expected to debut in North America on November 15, 2001.

The Xbox hardware consists of a 733 Mhz Intel processor, a custom Nvidida graphics processor based on the GeForce 3, and 64MB of DDR RAM which is used by both the CPU and GPU.

Given Halo's long development cycle and the uncertain date of its release for the Windows and Macintosh platforms, it is not currently possible to speculate as to what the system and 3d acceleration requirements for it will be, except perhaps to say that hardware 3d acceleration will most certainly be required.
