I've noticed that the "properties" box of running tasks tells me the speed that the task is running at. Now while i assume that this is how fast the computer is crunching the task I note that it varies between tasks on the same CPU. Why is this ? it is related to the FSB speed ?

Do you mean the "Estimated computation size"? These are GFLOPs by the way, not GFLOP/s. As in FLoating point OPerations, not floating point operations per second.

This is the estimated flops value that the project puts on those tasks. These values can vary, even at the same project, for the same application, depending on the run time length of the tasks.
