LOL you tried to type in caps!
Back on topic, I would buy a complete bike if you are going to spend 2000. You should be able to find an 05 bighit for around 1700. Thats if you want to do DH. It isnt really the best climber. A full suspension isnt going to be very good for street, so scratch that off the list. I think you should keep the bruiser and use it for street. Maybe an enduro or mid-travel bike would be good.
