Do you hit swap on a regular basis?
How often do you deal with large data sets?
Is the disk activity on a lot?
You'll get the most benefit from the extra RAM if you answer "Yes"
to any of those questions. Even if you answer no to those questions,
you'll still see some benefit.

Use a swap file. "man mkswap" has an example of how to make a
swapfile. Then format it, and add a line to your /etc/fstab :
/swap/swap001.swap none swap sw 0 0
Before kernel 2.6, swap files had a big performance hit, but now
are almost the same as partitions. And much more flexible.
