Yes, I think 800 MHz is right with a 400 MHz DDR RAM interface. That's what I expect anyway. I don't know of any faster RAM that's reasonably priced to push it any faster than that. The 970's native bus is only 100 MHz higher (900 MHz). So that will be close enough I think. k "T-Minus 2 Weeks And Counting" <http://www.apple-zone.com> "iPod Old vs. New - A Comparative Analysis" <http://www.ipod-zone.com> "Loophole Lets Big Hard Drives Inside Cubes" <http://www.cube-zone.com> On Wednesday, June 11, 2003, at 09:26 AM, Daniel Brieck wrote: > What speed should the next generation mac bus run at? > > I would say about 800 MHz. > > What does everyone think the bus speed should be at?
