Well, yeah. But do you need that kind of bus speed? Maybe to have a whole lot of tracks going, each with a dozen plug ins. But 500MHz should be OK for a lot. It's actually 533MHz (not a big difference, but just splitting hairs), and I've used less. Granted, I 'print to tape' and use no plug ins. But I have a hunch that's more RAM dependent and less processor speed. I could be wrong. Speed is important, but after a point, you may not notice. It may still be up to how much RAM you have.
