Hi Hal, With all else being equal, the dual 1.33 will smoke the 1.5 in Photoshop, iMovie and iDVD. I don't believe that VPC is dual processor aware, however, and many games aren't either. I guess it's a trade-off. Going forward, you may find that the dual processor will become more significant as more programs become multiprocessor aware... if it was my dime, I'd go for the dual. smiles, Jamie On Nov 12, 2004, at 11:12 PM, Hal wrote: > I'm considering upgrading a Quicksilver 867mHz G4.
