In oposition to what Bruce wrote: My computer _was_ a Quicksilver 2001, single 733 MHz. I then got a 1.4 GHz OWC Mercury Extreme, running Mac OS X 10.4.11 on it with various applications (Photoshop, just to name one). I did (as I always do) switch alot between the running processes. I then replaced it with the original Dual 800 MHz for this QS2001. The subjective feeling was that Mac OS X responded much faster to task switching and was generally more responsive. With the other programs I didn't see a big slow-down in any way, althou I didn't do extensive testing. So it may well be that a Photoshop filter was now slower because it may only use one CPU for the task. Personally, I would stay with a Dual system. And like Len wrote, replacement Dual processor cards are very expensive - you should propably go for a newer Mac in that case.
