Narrative:

We were shooting the lda DME approach. The center controller was very busy and never told us to switch to tower. When we turned inbound on the final approach course; we decided to switch to tower at a 13 mile final. When we got to tower; they started pointing out traffic alerts. Then we got a TA. We were searching for traffic; then we got an RA. We were at 11;200 feet and the traffic showed at 10;900 feet. I never saw the traffic. I followed the RA of 'maintain altitude;' and the traffic was still coming at us. I decided to do a go around and climb away from the traffic. After a couple seconds; we got a clear of conflict and then executed the missed approach procedure. We advised tower and center of the RA.the cause of the event was the controller being too busy to handle all the aircraft in the sector and the general aviation not following instruction from tower to stay south of approach course. I suggest letting [the nearby] airport to have its own approach control.
