The added RAM will certainly help to minimize or reduce swapping, if it is
occurring. But you might want to post the output of "vmstat -s" after the
system has been under normal load for us to evaluate how much benefit you're
likely to see.
With regard to what I assume you have is a 440BX chipset, the RAM requirements
for it seem to be [1]:
