Depends on how much RAM-intensive stuff you're doing.  Linux will cache 
frequently accessed data in RAM, so if you're serving up "static" HTML, 
etc, it will be read from RAM vs disk as long as it keeps getting accessed 
every so often.  You will get some performance boost out of that, as the 
disk access is a high penalty compared to RAM access.

How badly is your server getting slammed now?  Are you swapping to disk at 
all?  Are you getting Active Monitor alerts about low memory status? If 
not, you probably have enough RAM, and I'd save the money for now.

If you're not sure, shell into the server and run 'top' to see how much 
swap space is being used, etc.
