Dune 2 - I'm speechless, what have they done

[grs]

I wasn't claiming 300%. There were other factors like the amount of plugins on other tracks etc.
But I would definitely state a good 90% more. The project I was working on had two or three frozen Spire instances that when opened on my new PC were un-frozen and I continued working with more freedom to mix an add more programming and arrangement. This is my real world experience.
A DAW full of plugins may be capable of handing out tasks to threads for CPUs to take advantage of. The new architecture in the i7-4770k has way faster bandwidth to the Memory and a zillion other improvements. I don't have to sell it to you anyway, the only thing is what suits the end user and in my case I always believe in a good upgrade. You see and smell all that new PC goodness and your productivity ceiling gets raised a great deal.
