One thing to consider as well is the app you use:
depending on the application it might be a wise decision to pay a little more for a 4MB cash chip (currently: get a Core 2 Duo 6320 to get the best for buck :) ).
Because with more cache the CPU can prevent itself longer from using the RAM. No mather how fast RAM is, first and second level cache are seriously faster than RAM ever will be as they are on die. (AMD believed in the myth that an on die memory controller can bypass that and make the RAM a cheap third level like cache ... at least until they were stomped and burnt by core technology)
