Yesterday the DesktopBSD team released the 3rd RC for version 1.6.

What's new from the announcement:
  • X.Org release 7.2, improving support for modern graphics hardware
  • NVIDIA graphics driver, providing hardware 3D acceleration for NVIDIA video cards
  • Latest FreeBSD 6-STABLE as base system with High Definition Audio (HDA) support
  • Support for multiple processors and multi-core CPUs
  • More up-to-date software packages from the DesktopBSD build servers
  • Many small bug fixes and optimizations
See the announcement here.

I have not had the chance to test it other than in liveCD mode but I will update once I have had a chance to do so. Try it out.
