Narrative:

On vector to downwind for visual approach to runway 5 at orf at 5000 feet; heading 240 degrees; ATC called out traffic on the nose at two miles and 500 feet above. The first officer and I looked for traffic and very quickly got traffic alert from TCAS. We very quickly got a RA to descend. I quickly turned off the autopilot and auto-throttles and descended the aircraft until the RA stopped. We both saw the small general aviation aircraft very close off our left side and about 400 feet above our aircraft. It appeared to me that this aircraft was left wing down maneuvering to avoid us. I asked the ATC controller why he didn't vector us away or descend us sooner to avoid this situation which was uncomfortable. I thought ATC could have done a better job since there was very little; if any; traffic in the area or at the airport at that time.
