Wish I got a quid every time I heard that myth propagated. On my 2850 
which is used as a build machine, I see an approx. 25% improvement on a 
eight-way parallel build with it enabled. I'm willing to accept that it 
probably depends a lot on your workload and how many tasks are going, 
but it's wrong to say that it is of no real benefit in all cases.
