Hello,

Really, that is equivalent to the question "How long is a piece of string".

One thing that is important is that if you are going to get 8GB of 
memory, you must make sure you install the 64-bit version of Windows (or 
whatever) and the 64-bit version of Mathematica - otherwise, most of 
that memory will just sit there idle.

I would tend to go for Opterons, if only because AMD took a big risk in 
introducing a rational 64-bit architecture and forcing Intel to follow 
them - they deserve to get the business!

Before spending a lot of money, it may be worth getting someone to look 
at your code because it is very easy to write Mathematica code that 
works, but is horrendously inefficient.
