If I have a fixed amount of money to spend as a general rule is it better to buy one 
processor and lots of memory or two processors and less memory for a system which is 
transactional based (in this case it's handling reservations).  I realise the answer 
will be a generalised one but all the performance bits I've read seem to talk about 
adjusting memory allocation.  The client has received the general advice from their 
hardware supplier that 2 Xeon processors and less memory is better but for postgresql 
I'm thinking they might be better off with a single processor and loads of memory.  
The OS is Red Hat Linux.

How long is a piece of string  I guess but all comments welcome!
