Based on my experience (YMMV) I would rank your factors as follows:

1. RAM
2. More RAM
3. Even more RAM
4. Mirrored disk (if you are looking for bang for the buck you are best off avoiding RAID 5 -- like the plague)
5. Number of CPUs
6. CPU speed

   ---

I'd modify that list only slightly:

1. RAM
2. More RAM
3. Even more RAM
4. Hard disks
5. Hard disks
6. Hard disks
7. Hard disks (repeat ad infinitum)
8. Number of CPUs
9. CPU Speed
