Sad we won't see anything worth buying till March, and even then I would
probably want to wait another 3 months to make sure the boards and bios
have ALL the bugs worked out like I always do before upgrading.

Intel's 45nm chips will be out for 3 months by March and may be the
better bang for the buck though from what I've read their boards won't
have much of a future upgrade path compared to AMD's AM2/AM2+ socket
boards.
