However, when you say logic processes what do you mean?  Let's say I have a quad core, is that 4 logical processors?


Yes. To over-simplify: if you have 4 CPU-intensive tasks that don't sleep or block on I/O, aren't being swapped out for other threads, and whose working set fits in the core's cache(s), you stand a better chance of keeping the 4 cores busy. Many real-life tasks don't quite fit within those boundaries.
