75-100% cpu load isn't necessarily bad. What's the load average and specs for the box? What do you see in top using the CPU the most/most often? With 1200 services and assuming checks every 5 minutes, any machine in the last decade should be able to handle that.

This won't help since nagios doesn't use a mysql backend.
