For a good image-processing system, you need to add a zero to the RAM and
disk space, and add at least 2-5 inches to the monitor size and make it a
high-end monitor (I prefer Sony).  Configuring multiple disks as a RAID
would be even better, since the defective memory management of Photoshop
often must be compensated by fast disks.

Processor speed is rarely an issue.  About 99% of the delays I see in
Photoshop even with a 1.8 GHz processor are caused by disk I/O.

Overall, you can never have too much memory, too much disk, or a processor
or disk that is too fast.  However, many vendors (and buyers) place too much
emphasis on processors speed, and far too little emphasis on the other
characteristics of a configuration, even though these latter characteristics
are usually much more important.

Also, the utility of a good monitor cannot be overemphasized.  And a
digitizing tablet is essential, too.
