Bus Speed vs. Processor Speed.

I have two processors available to me, I'm going to be building a dual cpu system using two of either one. The mother board I'm using supports 1333MHz FSB.

The first option is the Intel QVQU

  2GHz Intel Xeon, 1333MHz FSB, Quad Core, 8MB Cache

The second option is the Intel QQMV
   http://www.cpu-world.com/sspec/QQ/QQMV.html
  2.66GHz Intel Xeon, 1066MHz FSB, Quad Core, 8MB Cache

So I need to decide, do I go with 2 of the QVQUs or the 2 of the QQMVs?

What do you think is more important the addition 667mhz or the 333 Mhz in bus speed?

If you take RAM that is the same speed as the other  2, the fact that the ratio will be 1:1:1 will be faster than having 667mhzs more for data intensive tasks.  

But for pure calculation, the 667 mhz would be better.

It depends on what the computer will be doing most of the time.  

I would take the 1333mhz one and overclock it to the speed of the other one :P
