cpu is quite important when you are appling effects

ram is very important especialy when you are working with large and/or multiple files

graphics cards are not really that important

RAM mostly but other do contribute too significantly in one way or the another.
It's based on which version of PS you're using,

for Photoshop CS3, a P4 CPU, more than 1GB RAM (memory) , a high speed hard disk driver (%26gt;=7200 rpm), any modern 3D-accelerate graphic card (NV or ATI or INTEL, %26gt;=128MB video memory) will be fine enough,

for your original question, I believe RAM and HD are more important for file operations, CPU and RAM are more important for pixels operations,
