Of course the OS will still load balance multiple single-threaded applications across the multiple cores. But you're right, going from 1/4 thread load to 1/6 thread load is less impressive than dropping the load by 1/2 by switching from single to dual-core or dropping from 1/2 to 1/4 via quad core.
