Fact is todays CPU's can do anything & everything, im not even concerned about its cpu anymore.
Yeah, same here actually, and I do pretty CPU intensive tasks. My MB C2D 2.0GHz is plenty fast, and I rarely run out of CPU even when mixing pretty large projects with lots of plugins.
Sure, a little more speed would be useful sometimes. But I'd not have it at the expense of for example a louder cooling system.
